We have a 15 week old Cavalier named Ollie. The breeder had been feeding him that raw beef diet. Our vet mentioned that because of bacterial concerns (we have small children), we might want to switch to a dry dog food. He suggested mixing the two at first. That was going well . However, For the past two days, Ollie has refused the kibble/raw mix. He'll gobble up anything my kids give him, but he won't eat either the dry or the raw dog food. Also, he seems to have very watery poop (sorry!!). Any suggestions?
