Do Dogs Need Vitamins?

I recently got a question from a long-time listener who asked if it was okay to give the dog a partial serving of their multivitamin-multimineral. I didn’t have a clue—I don’t deal with supplements and animals, with the exception of glucosamine and fish oil. Both are good for dogs, but what about the rest of the supplements?

One supplement I know they don’t need is vitamin C, because dogs can make their own vitamin C. In fact, only humans and one variety of bat can’t make their own vitamin C; all other mammals can. While too much C can be hazardous, the amounts found in most multis for humans should be fine for dogs. But what about the rest of the vitamins and the minerals?

Wouldn’t you know that the same organization, the National Academy of Sciences, that establishes the Dietary Reference Intake for humans has done the same for dogs. In examining the list, they’re in proportion for what humans would take, but proportional based on body weight. The document also goes through the entire nutrition lifecycle of a dog.

And before you ask, we’ll talk about cats on Thursday.
