The Big Miss: Is No-Hide® Actually Rawhide?

/

A ‘consumer advocate’ recently stirred up drama from July 2017 re-circulating an article (figure 1) claiming that Earth Animal No-Hide® treats were rawhide, again. This was on the heels of the announcement of a class-action lawsuit (figure 2) against Earth Animal Ventures (EAV) questioning the ingredients and sourcing of No-Hide® products. I didn’t think I would have to address this issue, but apparently, I do since misinformation and cherry-picked information from the original chain of events keeps circulating (if it’s on the internet it must be true, right?). Consumers and retailers alike need to see the situation for what it is, so I’ll also write this from both a retailer and consumer standpoint to provide the level of transparency I hold others to. As you read this, you’ll understand that both sides have significant issues. In fact, No-Hide® being (or not being) rawhide is hardly the issue. Instead there is a pervasive lack of transparency and misinformation from both the consumer advocate side and EAV.

Grain-Free Pet Food Diets | What to Know Before Switching

/

The benefit and necessity of grain-free pet food have come under scrutiny in recent years due to an FDA investigation due to a potential association with a canine heart disease known as dilated cardiomyopathy (DCM). As a result of this potential association, many have been told there is no scientific evidence to support the use of grain-free foods in canines and felines, or that these foods do not provide any benefit over grain-inclusive foods. For the most part, grain-free refers to kibble, although some have also categorized various canned, freeze-dried, and raw diets under the ‘grain-free’ umbrella. But are these claims accurate? Let’s find out:

 

Grain-free foods don’t provide benefits?grain free dog food kible

The pet food industry’s switch to grain-free was not fueled by a problem with the grains themselves or grain allergies like most believe. The largest pet food recalls in history was due to melamine and cyanuric acid contamination of ingredients coming from China. The short version of the 2007 recall is that wheat gluten and rice protein were intentionally combined with melamine for its high nitrogen content. Higher amounts of nitrogen can cause the protein content of an ingredient to test higher than it actually is. Since cyanuric acid was present, and the combination of melamine and cyanuric acid is likely the reason the recall was so deadly – not the melamine on its own. This series of events fueled the consumer trend of wanting grain-free pet food.

Other Concerns

Another major factor absent from the discussion on grain-free vs. grain inclusive diets for people – and pets – is the contamination of grains with herbicides, pesticides, mycotoxins, and fertilizers. This has become an increasingly large concern since the mid-’90s in both the human and animal food supply. Numerous peer-reviewed articles are detailing the disruption many of these agricultural contaminants have on normal gut bacteria function.1,2 In fact, available literature suggests that humans are becoming increasingly intolerant to grain and grain products for exactly these reasons (e.g. wheat & gluten sensitivity & celiac disease in humans).

We are learning that disruption of vital gut bacteria balance can have devastating effects on the health of the host, including diabetes, obesity, autoimmune disease, cancers, GI issues, and even DCM.3–5 Could the contamination of grains in pet food be one reason why many pets experience improvement of various issues with the change from grain-inclusive to grain-free? Could be.

Ultimately the phrase ‘there is no evidence to support the use of grain-free foods’ doesn’t mean there is not a benefit. It simply means that we have a major gap in research into companion animal nutrition and that we easily forget our recent history. On the contrary, we don’t have evidence to support that feeding grains to canines or felines are any more healthful than feeding grain-free diets. Evidence only shows that it meets minimal (known) nutritional standards, not that pets thrive on these processed diets. In short, canine and feline nutrition fields are far behind the knowledge we have in livestock and human nutrition.

 

Are ALL grain-free foods the same?

Many veterinarians and pet owners automatically lump grain-free cans, fresh food, raw food, and freeze-dried products as ‘grain-free’. While this is technically correct – there are stark differences that make these foods different from their kibble counterparts.

Regardless of whether we are feeding grain-free or not, we need to consider the high temps kibble and canned foods are heated to during the manufacturing process. This high heat creates Maillard Reaction Products (MRP) which is the name for a series of reactions that is the product of sugar (carbohydrate) and protein when heated. These are also known as AGE’s or Advanced Glycation End Products.

MRP’s are responsible for the nutrient loss and associated with diseases like diabetes, cardiovascular disease, kidney disease, loss of cognitive function, allergies, periodontal disease, and chronic inflammation.6–12 This can mean things like arthritis, skin, and ear issues, an old injury that keeps resurfacing, bloating, IBS, etc. Also, there is a large amount of research to suggest that they are carcinogenic and accelerate aging.13,14

  • Heterocyclic amines are MRPs from cooking protein that increases with elevated cooking temperature. This phenomenon is more pronounced in meat than fish – and these increase with temperature and dryness of meat or meat products15.
  • Acrylamides are a chemical that forms naturally from starchy foods during high-temperature cooking. According to the European Food Safety Authority evidence from animal studies shows that acrylamides are genotoxic and carcinogenic: they damage DNA and cause cancer. And since we know so little about animal nutrition is it possible that much of the disease we’re seeing – including DCM – has at least something to do with the MRP’s that are in dry and/or canned pet food? Is it a coincidence that freeze-dried, fresh, and raw options do not have as many associated issues as their processed counterparts? Maybe.

 

Allergic to Grains? Probably Not (sorry, not sorry)

Pet food can be made of everything from rendered unfit foods for human consumption to ingredients that are 100% organic and probably better than the food we feed ourselves. I’m not necessarily here to split hairs on ingredients and in the types of ingredients that are in our pet’s food. Because is it these ingredients that are causing the problem? Or is it something else? – These are the questions that the experts seem to avoid entirely. When a dog experiences issues related to food, we are quick as a society to turn over the bag and blame an ingredient or set of ingredients. However, those ingredients as listed are likely not the problem – rather the quality, processing agents, AGE’s and contamination of these ingredients (e.g. herbicides, pesticides, etc.); something you will never find listed on a label.

 

More Important: Nutrient Availability & Digestibility

The digestibility of food is altered as it is processed, mixed with other ingredients, and heated. That said, canned and kibble foods by definition will have varying levels of nutrient availability and digestibility than their lesser processed counterparts. The ingredients (or set of ingredients) that make up a food could be the most nutrient-dense food available – but if they are not digestible by the cat or dog then those ingredients are irrelevant. In short, this means that it is important to ask your pet food company for their digestibility and nutrient analysis to determine if their food is adequate for your pet. Learn more about what questions to ask and why here.

How To Switch Your Cat’s Food

/

 

Have you ever tried to switch your cat to a new food without success? This is actually a common problem with cats, so rest assured you’re not alone! Switching your cat’s food can be stressful for you and your cat. Before you start there are a few important things to consider.  Switching your cat to a new food can be a challenge, but with careful planning, you can increase the chances of a successful transition. In this guide, we will provide you with practical tips to introduce a new food to your cat without stress.

Tips for a Smooth Cat Food Transition

  • Relax. Believe it or not, getting stressed before you even switch the food can also stress out your cat. Be sure to set the right tone by not drawing extra attention to mealtime or making a big deal about the new food.
  • Be sure to have 3+ weeks of your cats’ regular food on hand, this will be enough to fully transition.
  • Begin with clean bowls or feeding platters. You should be in the habit of washing bowls daily to prevent unhealthy bacteria from building up.
  • Believe it or not, bowls should be made of glass, USA food-grade ceramic, or a safe plant-based material. For more on this click here: Is Your Pet’s Healthy Food Being Served In A Toxic Bowl?
  • Cats can actually develop an aversion to food based on the size of their feeding bowl. Bowls for food and water should be wide and shallow so cats’ whiskers do not hit the sides of the bowl. This is a phenomenon called whisker fatigue and it leads people to believe their cat is picky when in reality it may be that the bowl is irritating them. In fact, saucers or plates are actually best!
  • Decide what you’re going to switch to, as there are countless options. Consider protein, texture, sourcing, and any health conditions at play. Textures of canned/wet food include pate, shredded, or stews. For raw food, some can be chunky or finer in texture.

Week-by-Week Transition Plan:

how to switch cat food

Week 1: 

You will only use a pea-sized amount of the new food at each meal. If you are using cans or pouches you can try and store them in the fridge for 2-3 days. However, most cats do not like cold food. Be prepared to throw away a fair amount of cat food in your first 1-2 weeks. If you are using raw food, it becomes a little easier as you can thaw small amounts at a time since many raw cat foods come in convenient little kibble-sized pieces that thaw quickly. Regardless, be sure that when you offer the food to your cat that it is at room temperature.

Simply take a pea-sized amount and spread it thinly and evenly along the entire bottom of the dish you are using. Then, take your normal food (kibble or wet) and put it directly on top.

Notes for Success

At this point, it is important to not mix the food. The small amount in the bottom of the dish is to simply introduce the aroma of the new food, and not necessarily get them to consume it. Serve the meal as you normally would without making a big deal about it. Be sure that you do not hover or stare at your cat – simply go about your activities as you normally would. Cats tend to pick up on energy and stress, and you want to avoid introducing any new variables.

It is normal for your cat to not eat any of the new food or maybe leave and return to the dish a few times before eating their regular food. Again, try not to make a big deal about any new behaviors. They should be used to the smell of the new food within a few days. You may find them even starting to lick the bottom of the bowl and clean the dish by the end of the first 5-7 days. This is a good sign, however, be sure not to increase the new food too quickly as to avoid digestive upset.

Pro Tip:

By day 3-4 of week 1 you may choose to take one teaspoon of warm water into the dish prior to adding your regular food if your cat is showing interest in the new food. This can promote an appetizing smell and help to increase moisture intake. At the same time recognize that this is the most critical week, be sure not to rush! Patience is key!

Week 2:

By this point, your cat should have shown some interest and consumed some of the new food at the bottom of the bowl. At this point, you may increase the wet food to 1-2 teaspoons. Repeat a similar process at week one making sure the food is room temperature, with the new food on top. If your cat has seemed to like the added water, you may continue to add it.

By day 4-5 of week two, you may increase the food another small amount as long as they are consuming what you are already given.  Now is the time to consider cutting back on the dry food by a similar volume.

Weeks #3 & #4:

By this time your cat may be only interested in the new food, which is perfectly ok!  If this is the case, there may or may not be a little bit of loose stool as a result of the cat’s decision to switch to the new food abruptly. This should subside within a day or two as their system adjusts.

If they are still consuming both foods, then you can continue increasing the new food and decreasing the kibble as each day progresses. As mentioned above, the entire process can be slow and take 3-4 weeks or more!

Sometimes, they will begin to act hungry, and/or vomit bile when switched too quickly because the gastric pH and amount of secretion have not had time to adjust to the new food, especially in the case of switching from dry to wet food or raw food. If this does happen try offering a small “snack” outside of mealtime. This could include freeze dried treats, food or fresh meat.

Pro Tip: Cats tend to not seek out water as dogs do. While there are biological reasons for this, this doesn’t mean that they should not have ample fresh, clean water available – ideally away from their food bowl. If your cat does drink regularly and you feed dry food, do not be surprised to see their water intake decrease as you move to a more moisture-rich food. This is normal!

Summary:

The most important aspect of switching your cat’s food is not to stress! Be patient, and consistent. These practices pay off in time. Be sure to always ensure your cat has access to water. As they transition to a more moisture-rich food you may notice a healthier coat, brighter eyes, and even more energy!  Your cat who may not have been too playful prior may have more vigor and energy for exercise – it may be worth investing in a toy or two!

How to Safely Store Dry Food

/

We’ve all heard it before—Keep your pet food in the original bag, do not dump the food into a plastic container. But why?

Proper storage of pet food is essential in maintaining freshness and keeping your pet healthy. Pet food storage containers are typically not airtight. Therefore, these containers allow unwanted air and moisture to get into the food. Aside from the unwanted moisture, the oils and fats from the dry food can interact with the plastic of the container. All of this can cause mold to grow and make the food less palatable, and enjoyable for our furry friends.

Most kibble is dried before packaging to ensure there is no added moisture. Therefore, it is our responsibility, as consumers, to ensure that the moisture-free level remains that same after purchasing. Manufacturers specifically design pet food bags to prevent moisture and to keep the contents as fresh as possible. 

So what is the best way to store dry pet food? The answer is simple– in the original bag, in a cool, dry location. If the bag has a zip closure, it is recommended to expel all air before resealing. If there is no zip closure, release the air within the bag, and roll from the top. If a pet food storage container is available, place the bag into the container for optimal freshness. It is also possible to place sealed food in a refrigerator or freezer. 

Hemp & CBD: Not All CBD is “Natural”

/

In part II we discussed phytoremediation, and why this is one of the largest hidden risks for those who give CBD to their pets or consume it themselves. To review, cannabis absorbs heavy metals, and many of the agricultural chemicals in the soil such as pesticides, herbicides, and fertilizers. If a company does not have processes and procedures in place that ensure their product is free from contaminants and is actually the concentration that is listed on the label. Don’t believe this is a real issue? Due to a lack of regulation, hemp products have the potential for significant risks.

Consequences Due to Lack of Regulationrisks of hemp products

Unfortunately, due to the phytoremediation properties of hemp, contaminants and formulation errors are common and often go unnoticed. For example, a recent study by Cornell University showed 10 out of 29 CBD products tested were within 10% of the concentration on the label.  That same study also showed that heavy metal contaminants were found in 4 out of 29 products.19 Stop and read that again – because it means that only 34% of the most popular CBD’s were even the correct concentration. Never mind those with contamination issues…Yikes!

Spoiler alert: these are some of the most popular pet CBD supplements on the market today. Most of them are sold locally to Cheshire – so you may want to pay attention.

Lack of regulation for CBD means that companies who are NOT members of the NASC are not required to test raw ingredients or finished products for contaminants or adequacy. Heavy metal contamination, poor sourcing, and/or formulation errors could potentially be a contributing factor to elevated liver function testing and other documented adverse effects relating to hemp & CBD use. This highlights the need to screen companies for adequate product testing and transparency. The reality is that a very small handful of companies can provide verification that their products are contaminant-free, or within concentrations listed on the label.

Ask Questions Verifying Quality

When looking for a CBD product, or any supplement for yourself or your pets you must ask the following questions:

  • Are you a member of the NASC? (pets only)
  • Do you inbound test your raw and concentrated ingredients for contaminants such as heavy metals, fertilizers, and other agricultural chemicals?
  • Do you test your raw ingredients specifically active ingredients to ensure their concentrations are correct?
  • Do you source any ingredients from China?
    • Are you willing to provide certificates of origin?
    • Note that ingredients from China are not necessarily bad if they are responsibly sourced, and they are verifying quality and purity.
  • Do you complete an analysis of your final product to ensure the formulation is correct and ensure there are not any contamination issues? This is important to ensure that active ingredients match the label.

If companies are unwilling to transparently ask these questions or use the excuse of information being proprietary, I would strongly suggest that you find another brand. Not being transparent or testing products when it comes to ensuring safety is unacceptable. Brands that are not meeting these standards could potentially be poisoning the market for other companies who do their due diligence. As consumers, demand better.

Summary

CBD may have its benefits when well-sourced and formulated. While more research is needed, this is a common problem for a lot of supplements and pharmaceuticals on the market. Overall, the risk of adverse effects appears to be low, but consideration should be taken for those pets who may have liver problems.

Some veterinarians are well educated in the CBD landscape and available products, and some simply are not. If your vet is unable to provide information or recommend products it is ok to ask them for someone who can. Many reputable companies do have veterinarians and scientists on-staff that you or your veterinarian may also be able to speak to for more information.

As always, this is a rapidly evolving field. We expect to see changes as the FDA and AVMA begin to release more guidance and information in this area. We also will see more research regarding safety, efficacy, and other applications as time goes on. While it can be frustrating to see both advice and information change, remember this is a good thing and something you should embrace and support!

CBD & Hemp: Legal or Illegal?

/

In Part I of our CBD Education Series we discussed the history of cannabis, which dates back over 6,000 years! We know that hemp and marijuana are both types of cannabis and that THC and CBD are just two types of cannabinoids out of over 400 that exist within cannabis. Even though we’re waiting for research to catch up to the popularity of CBD, we explored how CBD works and the different types of cannabinoids that can interact with the endocannabinoid system of humans or pets. However, Hemp and Marijuana plants can be highly toxic. We are going to discuss the safety and legality of cannabis In Part II of our CBD Education Series. In addition, we’ll explore the FDA stance, the Farm Bill, CBD commerce, and other safety measures. Maybe a bit boring at face value, but if you use CBD for yourself or your pet it would be wise to familiarize yourself with the details.

Legality & The FDA 

As it currently stands the FDA has not approved a marketing application for cannabis for the treatment of any disease or condition.9Further, based on the Food, Drug, and Cosmetic Act (FD&C Act) CBD is illegal because it is recognized as a drug for human epilepsy. Based on the historical actions of the FDA, its current status as an approved drug establishes a low likelihood of CBD being approved as a supplement or food ingredient, but this has not stopped companies from using CBD in supplements and treats. The FDA is unlikely to enforce this legality if companies eliminate the use of ‘CBD’ on the label and avoid claims such as ‘cures, treats, prevents or mitigates’ a disease or condition. Many companies have complied, but unfortunately, some companies have continued to use ‘CBD’ on the label, and/or make unsubstantiated claims. As a result, the FDA regularly issues warning letters to companies who make these claims.10 In addition, it is important to note that CBD is not legally able to be included as an ingredient in pet food.

The rules and regulations for hemp and marijuana are different with each having separate statutory definitions:

  • Marijuana typically refers to plants with high concentrations of THC, the psychotropic drug used for medicinal or recreational purposes.1
  • In contrast, hemp is typically cultivated for use in personal care products, nutritional supplements, and fabrics. It contains higher amounts of CBD, which does not have psychotropic properties.3 THC must remain at a concentration of 0.3% or less on a dry weight basis.

The Farm Bill & Decriminalization Clarification

In 2018 the Hemp Farming Act (part of the Farm Bill), decriminalized hemp and lifted the ban on hemp as an agricultural commodity. The act also removed industrial hemp from Schedule I of the Controlled Substance Act (CSA). However, contrary to popular perception, it did not make hemp products, including CBD and activities surrounding their commerce legal11. Marijuana continues to remain a schedule I substance as of the date of this publication.12 As discussed earlier, the difference between these two being that hemp contains a very low amount of the psychoactive compound THC. The move to decriminalize hemp, and allow for responsible use in veterinary medicine is one that many veterinarians support, as many recognize its potential benefit according to a recent survey.3

Without formal regulation and guidance from organizations such as the American Veterinary Medical Association (AVMA) and the FDA regarding CBD use it leaves a lot of unknowns, and potential room for problems. The AVMA has pressed the FDA for regulatory action and clarification citing its potential therapeutic benefit.13  What many don’t understand is that much of the lack of guidance from these organizations has largely to do with a lack of data and research. The FDA currently is working to support drug development from CBD, and actively collect research surrounding its use. The FDA states, as data become available that are high-quality, reliable, and relevant to our evaluation of CBD products that fall under the FDA’s purview, we will be able to refine – and, perhaps in some cases, revise – our thinking and approaches9.

Toxic Cannabis & Phytoremediation

One of the most glaring problems within the hemp and supplement market is the lack of accountability and product adequacy testing. When it comes to toxic screening, cannabis in all form are of concern, because it can be a highly toxic plant. This is because it performs a process called phytoremediation. Meaning that cannabis absorbs heavy metals and many of the agricultural chemicals in the soil such as pesticides, herbicides, and fertilizers. Many companies like to hide behind proprietary when it comes to analysis or ingredient sourcing, however, it’s not an excuse that holds any weight when it comes to the safety of cannabis, period. Fortunately, the National Animal Supplement Council (NASC) works with some CBD companies to help protect against contaminated CBD products and other supplements from entry to the marketplace. In other words, it is wise to avoid pet supplements without the NASC seal. We’ll explain a bit more about the NASC below.

So How is CBD Allowed on The Market?

In short, it’s not – but there is light for use of CBD in pets. In fact, the National Animal Supplement Council (NASC) works in close communication with the FDA to establish quality and safety guidelines for all supplements, including CBD. This non-profit organization indicates that products with its seal are from companies committed to quality, vigilance, and continuous improvement to promote the well-being of companion animals and horses.  Members (manufacturers of pet supplements) must agree to adhere to NASC’s quality standards, part of which includes an independent audit to ensure conformance with quality system requirements. In order to use the NASC seal, members must follow the guidelines of the organization and demonstrate a commitment to responsible conduct in the industry.14

While CBD products are illegal by FDA definition many companies have been able to offer these products to consumers by working with the NASC and following strict policies to produce them. One of the most important aspects of this relationship is the Adverse Event Reporting System. An adverse event (AE) refers to a complaint involving animal health or nutritional supplement linked to any negative event that may be associated with the use of a product. Each member of the NASC is required to investigate and resolve every AE. Additionally, all AE’s must be reported to the NASC each month. This robust system tracks AEs by ingredient and product, with the system and information being available to the FDA14. 

Because of this system the FDA can view and track potential problems and investigate further if needed. Further, if CBD manufacturers do not use the term “CBD” on the label or make claims referring to the cure, treatment, prevention, or mitigation of any disease or condition it is likely the FDA will not enforce the issue at least at this time. As stated earlier, ongoing research projects and results may influence this in either direction in the future.

Summary

Simply put, CBD supplements and other products are not legal. However, since they are already produced and consumed in such high volume without a large number of adverse effects the FDA has eased enforcement of companies operating safely. The same cannot be said for companies who risk safety by cutting corners with sourcing, labeling claims, and/or adequacy testing. The FDA recognizes that CBD manufacturers who are operating in good faith want regulation and they also recognize that the medical communities are seeing positive results for their patients. However, until quality data are available to support claims and benefits it is unlikely the FDA will budge in its formal stance on the issue.

In Part III we will discuss the data that is and is not available for short and long-term CBD use in pets, as well as information on giving CBD to your pet. We will also explore the documented risks of hemp and marijuana in pets, and what to do if you find that your pet has ingested marijuana. Did you miss Part I in the CBD & Hemp series?

CBD & Hemp: Hemp, CBD (and other) Safety Considerations

/

In part I and part II we discussed the history of CBD, how it works, and the legality behind CBD for pets & people. While this can all seem a little overwhelming, especially considering the wide availability of CBD – the main take away is that it is important to be safe when choosing any supplement. One of the reasons I decided to put together such a robust series was to explain why it was so important to look for quality and transparency in products. I can tell you all day that quality and transparency are important, but if I don’t explain the reasoning, it just becomes a hollow message.

Part III dives into the clinical data available for CBD use in pets. We’ll also look at what to do if your pet ingests marijuana. Unfortunately, this is a common incident, and THC within marijuana products is an emergency. Finally, we’ll discuss why there is not more available data on dosing, and just why this may be different for each pet.

Hemp & Marijuana: Available Data, Risks & Clinical Information

No established long-term safety data for Hemp/CBD in pets, however, this is not unlike many pharmaceutical medications and supplements already on the market.15 Recent short term data from a recent small study of cats and dogs given 2mg of CBD twice daily for 12 weeks determined that CBD was not detrimental to complete blood counts (CBC) or biochemistry values. It was determined that CBD in cats is metabolized differently than dogs, and needs further evaluation to determine appropriate dosing.4 Additionally, one cat experienced rising levels of ALT, a liver enzyme, which also requires further investigation.16 Additional studies have shown an elevation in ALP, another liver enzyme, further identifying the need for more research.17 This is in line with findings on the human side regarding use of CBD.18

Marijuana itself does have well-documented risks for pets that stem from THC. Even though this is not used or recommended for pets, exposure is common through the ingestion of their owner’s marijuana supply. The minimum lethal oral dose for dogs for THC is more than 3 g/kg, and has been seen most commonly with the ingestion of THC butter.4 Treatment of THC/marijuana ingestion in animals is largely supportive. Meaning that no specific antidote presently exists for THC poisoning. The majority of dogs experiencing intoxication after marijuana ingestion recover completely without long term effects or deficit.4

Clinical effects of toxic levels of THC/marijuana ingestion are generally seen within 60 minutes. Signs of canine intoxication include depression, hyper-salivation, mydriasis, hypermetria, vomiting, urinary incontinence, tremors, hypothermia, and bradycardia. Higher dosages may additionally cause nystagmus, agitation, tachypnea, tachycardia, ataxia, hyper-excitability, and seizures.4 If you suspect your pet has ingested marijuana seek immediate veterinary care.

Toxin Concerns: Phytoremediation

In our last article, we discussed the lack of accountability and product adequacy testing within the human and pet supplement market. When it comes to toxic screening, cannabis in all form are of concern, because it can be a highly toxic plant. This is because it performs a process called phytoremediation and therefore adds another level of concern to the equation. Phytoremediation means that cannabis absorbs heavy metals and many of the agricultural chemicals in the soil such as pesticides, herbicides, and fertilizers. Many CBD companies like to hide behind the word ‘proprietary’ when it comes to analysis or ingredient sourcing. However, this is not an excuse that holds any weight when it comes to the safety of cannabis, period. Fortunately, the National Animal Supplement Council (NASC) works with some CBD companies to help protect against contaminated CBD products and other supplements from entry to the marketplace. In other words, it is wise to avoid pet supplements without the NASC seal. We discussed the NASC in more detail in Article II.

Dosing for CBD Products

A variety of CBD containing products are on the market for people and pets. These include oral oils, pills, capsules & food products like treats and honey.  There are also balms and other transdermal-type products that are designed for use on skin. Products have varying levels of effectiveness that likely have to do with quality, purity, concentration, and dosage. Exact dosing of CBD dosing for pets is still being established and is largely up for debate. Further complicating this issue is that some hypothesize this could be highly individualized.

Fortunately, CBD containing hemp products, by law, are to have 0.3% THC or less on a dry weight basis, so the risk of overdose from THC is quite low.9 This does not however mean that dosing CBD, hemp products in pets should not be measured or monitored. Always follow veterinarian and/or product label instructions.

Summary

We’ve all heard the claims of benefits for CBD for both pets and people, however, we now know that those claims are largely unsupported by science and that companies are likely in violation when making these claims. Regarding safety, it appears that there are few adverse events. For CBD have been reported, however, some studies point to a potential for concerns for liver values. This area needs further research, and we’re sure that more data will be available in the near future. If your pet has had or currently has any liver concerns, it is important to discuss CBD use with your veterinarian prior to using it. In addition, if you decide to use CBD it is paramount to ensure the product is NASC compliant. There are also several questions that you can ask your CBD (or any supplement company) which we will discuss in Part IV! Did you miss part I and part II of the CBD & Hemp series?

CBD & Hemp: What is CBD and How Does It Work?

/

Cannabis: An Ancient Crop with Claims of Health Benefits

The use of cannabis dates back to ancient civilizations, with records of its use dating back to 6,000 years ago.1 Claims of health benefits included constipation, gout, rheumatism, and absent-mindedness.2 However, it wasn’t until recent years that numerous potential therapeutic uses of cannabis for pets have surfaced.

While there is more research for human use of CBD, animal research into CBD is lacking. The minimal research that is available needs significant expansion and validation. It’s important to remember that just because something is published, it doesn’t mean it’s entirely accurate or even applicable to the real world. Therefore, it is essential to understand the regulation, safety, and legality surrounding pet supplements.

Today, there is a plethora of CBD supplements available to people and pets. However, with so much misinformation and dangerous information on the market, it can be challenging to determine what is safe and legal. 

In this multi-part series, we will explore the regulation, how CBD works, and the safety and legality surrounding pet supplements. Since this article serves as our opening to the discussion, we’ll cover the basics: the difference between hemp and marijuana, how CBD works, and how it’s absorbed.

Classification & Cannabinoids

Cannabis can be broadly classified as either hemp or marijuana, and that classification depends on the concentration of the cannabinoid Delta 9-tetrahydrocannabinol (more commonly known as THC) and other cannabinoids they contain.3 The plants contain more than 400 chemicals but the cannabinoid THC is the one with the most recognition for its psychotropic “high” effect.4 Because THC is highly lipid-soluble and is distributed in fat, liver, brain, and renal tissue in the body.

The other cannabinoid that has gained attention is cannabidiol (or CBD), which is the focus of this discussion. It was first isolated from the marijuana plant by Roger Adams in the 1940’s, although it wasn’t chemically described until 1964 by Raphael Mechoulam. Today CBD is commonly used in a variety of human and pet supplements and edibles for pets and people. This cannabinoid has a lot of focus due to its potential, not proven, the ability to help manage anxiety, insomnia, and pain in humans. As already discussed, despite many anecdotal reports and claims more research is needed to determine the effectiveness, dosing, and safety of CBD and other cannabinoids in pets. However, as mentioned earlier, this is also true for many other types of supplements for pets – in fact, a lot of human data is used in order to promote the benefits to pets.

How CBD Works

There are three types of cannabinoids. Like neurotransmitters, all types of cannabinoids work by triggering a response from a receptor. Cannabinoids interact with receptors in the endocannabinoid system (ECS). The main function of the ECS is to maintain body homeostasis— which is biological harmony in response to changes in the environment.5  CBD is known as a phytocannabinoid, which comes from plants. For context, several plants beyond cannabis also produce phytocannabinoids, including cacao and echinacea. All mammals also produce their own cannabinoids, called endocannabinoids. The third type of cannabinoids is synthetic cannabinoids which are made in a laboratory. 

Phytocannabinoids, such as CBD work to inhibit the activity of ECS receptors, or in other words; limit activity or turn them off. The endocannabinoid system (ECS) has a role in the regulation of pain, pleasure, digestion, metabolism, inflammation, sleep, movement, neuroprotection, immune function, appetite, body temperature, mood, memory, and cardiovascular function.6,7  

Since CBD influences the ECS, there is potentially a wide range of benefits to the therapeutic use of CBD containing supplements and much of the theory behind CBD comes from this. Many anecdotal and case reports reflect these benefits; however, the problem is that there are few evidence-backed indications of these benefits in the mainstream scientific literature. This is complicated by the fact that many companies and non-scientific blogs continue to make claims of benefit giving the consumer and even retailers the perception of more evidence than there is. This climate has created a lot of trust and transparency issues for medical practitioners and CBD manufacturers.

There are two main cannabinoid receptors in humans and dogs, CB1 found primarily in the central nervous system and CB2 which are peripheral and immune-modulating.4,8 CB1 activity is believed to be responsible for most endocannabinoid clinical effects and benefits. 

Dosing & Absorption

CBD dosing & bioavailability, or the body’s ability to absorb CBD containing products are other factors to consider. There are several different types of products that have varying levels of bioavailability. For example, CBD itself is a fat-soluble cannabinoid, like THC. Since our bodies are mostly water traditional CBD oils not absorbed well in the gut, and therefore only have adequate absorption via the oral mucus membrane. Humans for example would need to hold a traditional CBD oil in their mouth for about 90 seconds for best absorption – not exactly realistic for dogs or cats. 

Fortunately, technology has offered solutions to the absorption challenges of traditional CBD oils. There are companies that have altered their products to be absorbed through liposome (fat) technology or nano-particle technologies that allow for oral use and absorption through the GI tract when consumed. The later technology has the highest bioavailability and allows CBD to cross the blood-brain barrier since the particles are so small. However – most CBD oils, treats, and edibles available are not nano-particle, so it’s important to ask. In addition, edibles, especially dog treats that have traditional oil have likely had a heat process applied (i.e. baking). Heat significantly reduces the bioavailability and therefore effectiveness of the CBD within the product. 

Summary

CBD can come from hemp or marijuana, with hemp lacking enough THC to product the psychotropic “high” effect marijuana is most known for. Although Hemp based-CBD supplements are widely available on the market, the reality is that there is a real lack of information regarding its exact benefit or benefits. However, we know enough about the human and animal endocannabinoid system to theorize how and what these supplements may be useful for. The type of CBD is important when choosing a product because not all are easily absorbed or effective due to a variety of processing techniques. 

This article is part of a Hemp Education Series. Over the course of this series, we will further explore hemp legality, safety, dosing, and how to spot quality from potentially dangerous products.
