Buying Guide

How do you know if your Pet needs Supplementation?

It is always a good idea to consult your vet if something just does not seem right with your pet. However, if you notice your pet’s coat looking dull or if they shed excessively, it could be an indication that they need some sort of supplementation. Itchy, flaky skin can make your pet miserable and implementing a supplement to improve skin health can provide relief. These signs are all good reasons to discuss supplement options with your vet.

What causes Skin and Coat Issues?

A lot of these issues can be blamed on imbalanced diets derived from poor quality food or homemade diets. Poor quality foods are typically full of fillers while homemade diets (even though well-meaning) can be imbalanced and still lack vital levels of needed vitamins and minerals. Even reputable brands that provide ample nutrition can have lacking ingredients that are not ideal for your particular pet.

Certain health issues and sensitivities can also create dry skin or hair that is easily damaged. Some pets naturally have vitamin deficiencies that can lead to flaking and itching. Neglecting your dog’s grooming needs or over-grooming can both also have adverse effects. Luckily, these all can be treated with a good quality skin and coat supplement.

Ingredients to Look For

This is a list of effective ingredients and their benefits to consider when choosing a supplement for your pet:


This is typically an umbrella term for a group of fatty acids. Of those acids, EPA and DHA are the most well-known. They are found in substances like fish oil or seaweed. ALA is another nutritionally important fatty acid that can be found in dark-leafed plants. Adding Omega-3 to your dog’s diet can aid in promoting healthy joints, heart function, and support a strong immune system. It can also help with itching, coat health, and kidney functions.


This can rarely be deficient in some pets. They are often found in commercial dog foods since poultry and vegetable oils contain Omega-6. Thus, most pets get plenty of this acid. If there is a deficiency it may present itself by giving your dog a very dry and brittle coat that easily falls out. They may also be infection-prone and have an insatiable itch. It can also cause reproductive issues, poor weight gain, liver and kidney degeneration, and immune issues such as slow wound healing. Omega-3 and 6 need to be supplemented when deficient because they are gained through their diet and cannot be produced naturally.

Vitamin E

This vitamin is an important nutrient that can counteract the effects of free radicals. Free radicals cause damage to cells and can do so at higher levels during illness and as a dog ages. Vitamin E is a potent antioxidant that helps with cell repair, immune support, reproductive health, and can also aid in keeping eyes clear.


Also known as vitamin b7 in dogs, biotin helps treat allergic reactions and skin conditions. It is especially effective when used in conjunction with fatty acids. It can also aid in digestive health, muscle formation, and general growth.

Vitamin A

Vitamin A helps to rebuild body tissues. Deficiencies can lead to a dull coat and itchy skin. Supplementing with vitamin A also provides lubricating benefits to the membranes that line the liver, kidney, and lungs helping them function optimally and ward off disease.

Vitamin C

Even though vitamin C is produced naturally in your dog’s body, it can deplete quickly if they fall ill or are stressed physically or emotionally. Vitamin C also helps strengthen their immune system. It enhances the antioxidant properties of vitamin E, increases the number of antibodies, and can act as a natural antihistamine to relieve allergies.
