I want to give my miniature pinscher an antioxidant supplement. I have read that Vitamin C can be harmful to a MinPin. I have then read the contrary on this page under the sub-heading Vitamin C: http://www.dogfoodproject.com/index.php?page=vitamins Could you tell me if it is harmful to supplement my miniature pinscher’s diet with vitamin C?
I am aware that dogs make their own vitamin C, so there is no need to supplement them with it, but can it be harmful to some dogs?
Thank you. JV
Thank you for your inquiry to Holistic Pet Info. Vitamin C works with vitamin E and helps regenerate vitamin E, potentiating its antioxidant effect. Vitamin C supplementation does no harm, since the excess is excreted through the kidney. If a dog has kidney disease or compromised kidneys, then supplemental Vitamin C is not recommended.
While dogs produce vitamin C in their bodies (unlike human beings and guinea pigs who must have it in their diet), under stress or disease, they may need vitamin C in excess of their manufacturing capacity. In excessive dose, vitamin C can cause flatulence and diarrhea.
I am not familiar with Vitamin C being an issue with MinPins in any Veterinary Medical research literature. Just as with people, there can be individual issues with foods and supplements for canines. The toxicity issues in other breeds are minerals and vitamins that are not water soluble and therefore stored in the body.
Ideally Vitamin C should not be an issue if the dog is on a well balance home cooked or raw diet. Fortunately, there are now excellent commercial dehydrated raw diets available for dogs and cats. Best of luck.
