Reading the info below, it looks like TOTW is a good choice for my 13 week old Bulldog. However, is it healthy to COOK food for my dog? Like chicken? Or is it best to give him raw or to always use dry food? I have always given my dogs the same food dry food, but want my Bully to be happy and enjoy his food. If we do use raw meat, should we buy this in the pet store and from the grocery store as we would eat?
