Exploring the Benefits of Vitamin C for Dogs: Insights from Our Vet at Dogster

Vitamin C, also known as ascorbic acid, is a popular antioxidant known for its health benefits in humans. Many of us take vitamin C supplements to boost our immune systems and overall health. However, when it comes to our furry friends, the story is a bit different.

Unlike humans, dogs have the ability to produce their own vitamin C in their liver. This means that for most healthy dogs, vitamin C supplementation is not necessary. The Association of American Feed Control Officials (AAFCO) does not list vitamin C as a required nutrient in dog food, further supporting the idea that dogs can meet their vitamin C needs through their natural production.

While some dogs with specific health conditions like portosystemic shunt (PSS) or severe liver disease may benefit from vitamin C supplementation, not all dogs with these conditions require it. It is important to consult with your veterinarian before adding any new supplement to your dog’s diet, as giving too much vitamin C can actually be harmful.

Many pet food companies add vitamin C to their products, but this is often for its preservative properties rather than its nutritional benefits. AAFCO does not require vitamin C to be included in dog food formulations, indicating that it is not an essential nutrient for dogs.

Research on the benefits of vitamin C supplementation in dogs is limited. While some trainers of high-level canine athletes give vitamin C supplements to improve performance, studies have shown mixed results. In some cases, vitamin C supplementation has actually been linked to decreased performance in racing Greyhounds.

One of the main concerns with vitamin C supplementation in dogs is the risk of long-term over-supplementation. Too much vitamin C can lead to the formation of calcium oxalate stones in the urinary tract, which can be life-threatening and require surgical intervention to remove.

In conclusion, while there may be some dogs who could benefit from vitamin C supplementation, it is not recommended for all dogs. For most healthy dogs, the risks of over-supplementation outweigh any potential benefits. It is always best to consult with your veterinarian before giving your dog any dietary supplement to ensure their health and well-being.
