I want to know what food i should switch my 4 month old pittbull to. I might switch him back to pedigree but i want to learn what is best for him. I would try barf, but i heard that it will make pittbulls to bloodthirsty. It sounds like nonsense to me, but i want to make sure, and i like keeping him on just kibble. What kibble is the best, or is raw food better?
