Logically speaking, no. Think about what wild dogs, wolves, hyenas, jackals, eat. Think about the mice, birds, squirrels, chickens even, that cats hunt and eat. Dogs and cats are biologically designed to eat raw meat.
It can happen that during the transition from pellets to raw food, some dogs and cats get upset tummies like diarrhea or even vomiting. This is due to the change in diet and does not mean there’s something wrong with the food.
