Brits are often called ‘Limeys’ by Americans, after British surgeon James Lind discovered that vitamin C-rich citrus fruit kept sailors’ scurvy at bay.
But what about vitamin C for dogs? Do they need to keep up their vitamin C intake? Can they have too little or too much?
Unlike humans, dogs possess the natural ability to make their own vitamin C in their liver,1 so you’ll be glad to know that, generally, they can get on fine without extra vitamin C supplementation in their diet.
Is Vitamin C Good for Dogs?
There’s no need to worry if you don’t find vitamin C, or any of the foods that naturally contain it, on your dog food’s ingredient list, as your healthy dog can take care of that missing nutrient all by themselves.
Vitamin C does have some benefits for certain dogs, though, which we explain more about below — mainly for dos who are ill or suffering certain health conditions. But for the majority of dogs, extra vitamin C in the diet or via supplements is not required.
Is Vitamin C Bad for Dogs?
Too much vitamin C can sometimes result in problems for your dog — issues can include diarrhea and gastrointestinal distress, bladder stones and urinary tract infections.
How Much Vitamin C Should Dogs Have?
Bear in mind the Association of American Feed Control Officials (AAFCO) nutrient profiles for dogs don’t include requirements for vitamin C in dog food as they make their own.
If you decide to give your dog vitamin C supplementation, whether it’s to help with a health issue or just as supplementation, experts suggest beginning with 18mg per pound of bodyweight, as that’s how much the average dog makes per day. Vets recommend dividing the dosage across your dog’s meals throughout the day.
Please note that if you’re thinking of giving your dog extra vitamin C, ensure you discuss your plan with your vet first.
