Why Your Pet’s Skin Issues Aren’t Always at the Surface?

/

Grooming is an essential part of owning a pet. But have you ever asked yourself why? 

Regular brushing, bathing and nail trimming can assist with not only the overall appearance of your pet but also have some physiological benefits. Brushing your dog’s coat regularly removes the dead hair, prevents mats, and even allows their coat to breathe and grow new hair. Brushing your pet is also essentially a massage—and who doesn’t enjoy a massage? It provides great bonding time between you both.

One of the more common issues that bring dog owners to NorthPoint Pets is a dog’s skin. Allergies, itchy skin, flaky skin, hot spots and more—are all common complaints from pet owners. But rather than looking at the obvious symptom—the pet’s itchy skin—we want to figure out WHY your pet is itchy and that starts in the gut. 

Our pets have good (and sometimes bad) bacteria in their gut. This colony is called their microbiome which is in their intestines and gut. The microbiome is essential for immune health, which includes our pet’s skin and coat. When the microbiome is compromised, their skin is also compromised. This results in a dull coat, a stinky dog, and more. 

The best thing you can do for your pet is to feed a good diet with an addition of fresh foods. We can also recommend supplements to help your dog look and feel their best!

 

Pet Food Allergies: Ingredient Quality and Processing Explained

/

Pet parents often mistakenly blame specific ingredients on their pet food label for their pet’s allergy symptoms. However, allergies to common food ingredients like chicken, beef or other whole foods does not make much sense. While pet food allergies do exist they are incredibly rare. What pets DO react to is the quality of the pet food ingredients and processing they go through. There can also be additional additives and other ingredients causing allergy symptoms – and they usually aren’t listed on the label!

Dogs & Owners May Suffer from Same Allergic Traits

/

A study published in Nature Communications found that owners and pets who live in a more urban environment were more likely to exhibit allergic symptoms. The reason? Both people and dogs in urban communities are limited in their exposure to healthy microbes that exist in a more rural or wilderness-type environment.

 

Interestingly, the increased ‘risk’ of allergies in an urban environment is largely attributed to lack of protective-effects. The protective effects include less exposure to livestock, western diets (e.g. American diet) and small family size. In other words, households with a lesser number of children, or no children and only 1 pet have a higher risk of allergies. According to another study, pet dogs have a reduced risk of allergies when exposed frequently to other animals as well as when living in a larger family.

Should I Feed My Pet Fresh Fruits & Vegetables?

/

Should we be adding fresh fruits and vegetables to our pet’s meals?

It seems like every week, we hear one thing and the next week it changes (like the great butter vs margarine debate). When it comes to our pets, nutrition is almost like a religion with many different beliefs and philosophies. Unfortunately, many of these arguments are based more on emotion than science. Although there is scientific evidence to support various nutrition philosophies, the interpretation of evidence can lead to potentially unsafe practices.

To make matters worse, marketing practices can further confuse pet owners and veterinarians, leaving them unable to distinguish fact from fiction. Despite this, we have seen significant shifts in recommendations for both humans and pets and diet-related diseases like insulin-dependent diabetes and obesity cannot be ignored. In humans, there is ample evidence to support a causal relationship between high intake of processed foods (containing refined carbohydrates/sugars) and insulin-dependent diabetes, obesity, and other metabolic-related diseases. It makes sense that we would worry about the same issues in our pets, considering that most dry pet foods contain between 40-60% refined carbohydrates.

Can Pets Digest Carbohydrates?

We know vegetables are important in the human diet, some more nutritionally beneficial than others, and the same applies to our pets. While the debate amongst many within the pet nutrition industry may disagree – our dogs are not wolves (read more here), and they can digest carbohydrates. While the ability to do this varies between various breeds, the focus of this blog isn’t the ability of our pets to digest carbs – instead, it is the benefits they obtain from fiber, antioxidants, and other phytochemicals contained within fruits and vegetables.

Our canines & felines need muscle meat, organ & bone partly due to the bioavailability of amino acids and other nutrients. If you were to give your dog the option of meat or plants/vegetables, studies show they would choose meat. However, when offered together, most dogs and some cats will consume fruit or vegetables too. Some trial and error with various cooking methods, chopping, mincing, or even blending in a food processor may entice those who may be pickier.

Why Supplementing Your Pet’s Diet with Vegetables is Importanthungry dog with fruit and vegetable bowl

As a pet owner, you may wonder if it’s necessary to supplement your pet’s diet with vegetables, especially if they don’t seem to like them. After all, isn’t pet food already complete and balanced? While pet food does provide the necessary nutrients, adding vegetables to your pet’s diet can provide additional benefits.

Vegetables and plants are abundant in vitamins, minerals, carbohydrates, fiber, and even beneficial bacteria. However, for pets that primarily consume canned and/or kibble food, adding fresh plant-based foods can provide protective benefits. Canned and kibble foods tend to have high levels of carcinogenic chemicals called advanced glycation end products, or AGEs.

The Negative Effects of AGEs

AGEs are naturally present in animal-based products, and additional AGEs form during the cooking process. Since dogs and cats primarily eat these types of food their entire life, their toxic load is much higher as a result. Toxic loads can negatively impact various organ systems, overall health, and even shorten the lifespan of pets and people.

The good news is that antioxidants and other phytochemicals present in fruits and vegetables, particularly leafy greens and berries, help to ward off some of the negative effects of AGEs. By adding fresh, organic, raw, or lightly cooked plants and veggies to your pet’s diet, you can help to reduce the toxic load and improve their overall health.

The Limitations of Commercial Pet Food

Even the best raw, kibble, or dehydrated foods lack the benefits of fresh, organic, raw, or lightly cooked plants and veggies. By supplementing your pet’s diet with fresh plant-based foods, you can help to provide a well-rounded and balanced diet that supports their health and well-being.

Fruits and veggies you can feed to your pets include:
  • Leafy greens (rotate for variety)
  • Green beans
  • Broccoli/Cauliflower
  • Summer squash
  • Blueberries
  • Watermelon
  • Pineapple
  • Apples

….just to name a few!

What Foods are Safe for Dogs and Cats?

While there are only a few things dogs and cats can’t have, quantity is what matters. Here are some guidelines to keep in mind:

  • Monitor Onion Intake – Large amounts of onions can cause Heinz body anemia in pets, but small amounts in tomato sauce are usually fine. Garlic is safe in moderation and may benefit the immune system, while also serving as an effective flea & tick preventative.
  • Avoid Grapes and Avocados – Grapes and avocados may affect pets differently, so it’s best to avoid them altogether.
  • Experiment with Fruits and Vegetables – It’s okay to experiment with new fruits and vegetables one at a time, and observe for any adverse reactions. Fresh and healthy table food can be shared with your pet in moderation. 
  • Cats and High-Starch Foods – For cats specifically, avoid high-starch foods like potatoes, pumpkin, and grain-based products. Cats lack adequate enzymes to digest carbohydrates. Instead, focus on low-starch vegetables that are rich in antioxidants to support their digestive system.

How much to add?

These additions for cats should be kept low, however, they can be added to dog’s diets in greater amounts. Cats should consume no more than 5%, and dogs should be no more than 15-20%.
