Dog Supplements for Homemade Dog Food: Which Are Best?

The health of our furry friends is paramount to us, and a well-balanced diet plays a significant role in ensuring this. While commercial dog foods are usually designed to provide a complete nutritional profile, there may be occasions when adding vitamins or holistic dog supplements could be beneficial. 

However, it's important to remember that supplement administration should always be under the guidance of a veterinarian, as excessive or inappropriate supplementation can be harmful.

Essential Vitamins for Dogs

A well-balanced canine diet typically includes all the necessary vitamins. However, in certain cases, additional supplementation may be required. Here are some essential vitamins and their functions:

Vitamin A

Crucial for vision, growth, and immune function. This vitamin is commonly found in liver and fish oils.

Vitamin B 

This includes vitamins like B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folic acid), and B12. B vitamins are important for nervous system function, energy production, and skin and coat health.

Vitamin C

While dogs can produce vitamin C in their bodies, additional supplementation can help with oxidative stress and overall health.

Vitamin D

Known as the sunshine vitamin, it's vital for bone health as it regulates calcium and phosphorus absorption. Vitamin D deficiency can lead to serious health issues in dogs, such as rickets.

Vitamin E

This acts as an antioxidant, helping to defend against oxidative damage. It also aids in fat metabolism and maintains healthy skin and coat.

Vitamin K

Important for blood coagulation and bone health.

Best Dog Supplements to Add to Homemade Dog Food

Besides vitamins, there may be a need for additional supplements, particularly for specific health concerns, breeds, or stages of life. Some commonly used supplements include:


These are beneficial bacteria that promote gut health, aiding digestion and supporting the immune system.

Glucosamine and Chondroitin

These supplements are often recommended for dogs with arthritis or joint issues, as they can help to maintain cartilage and joint health.

Fish Oil

Rich in omega-3 fatty acids, fish oil helps promote a shiny coat, healthy skin, and overall inflammation reduction.


Supplements like Coenzyme Q10 and other antioxidants can help protect against damage from harmful free radicals, potentially slowing down aging and reducing the risk of disease.

Fiber Supplements

These can help with weight management, digestive issues, and maintaining steady blood sugar levels.

When Should You Supplement?

Supplementation should be considered in consultation with your vet, as every dog is unique, and its nutritional needs vary based on breed, age, size, health status, and lifestyle.

For example, senior dogs may benefit from dog joint supplements, while puppies may need additional vitamins for their growing bodies. Other pups may have specific health conditions which require specific supplementation. One prominent example would be Canine Adrenal Support for dogs with Cushing's Disease.


While it may seem that adding vitamins and supplements can only be beneficial, inappropriate or excessive supplementation can actually lead to health problems, including vitamin toxicity. For instance, excessive vitamin A can lead to dehydration and joint pain, while too much vitamin D can cause kidney failure.

While most commercial dog foods provide a complete and balanced diet, certain circumstances might call for additional vitamins and supplements. However, this should not be a decision made lightly or without professional guidance. 

Always consult with your veterinarian before adding any new supplements to your dog's diet, to ensure that your canine companion gets exactly what they need for optimal health. Remember, the goal of supplementation is not to replace a balanced diet but to enhance it and to address any specific health concerns your dog might have.
