My dogs eat only raw meat. Cooked meat can remove important nutrients like vitamin C from the meat that dogs rely on. I also supplement my dogs with 150 mg/day of magnesium glycinate. I shudder when I see these prematurely aging dogs at the park, thanks to neglectful owners only feeding them scraps.

Like most mammals, dogs are able to synthesize vitamin C.

Humans and guinea pigs lost the ability to mutations.
