I have recently switched my 6 mo. Shepherd mix, Cujo to a raw meat diet. Good first week, we tried chicken livers, fish, eggs and some pork necks. He didn't like the livers or eggs raw so I cooked those up and he was loving it. After we ran out of that, I bought some sliced up pork and beef. He ate that raw no problem, but regurgitated it not a minute after. So then I tried cooking it and giving it to him a lot slower so he wouldn't eat it so fast. He didn't throw up nearly as much, but he still threw up a bit. Could it just be because he is full or maybe his stomach just doesn't like that mixture... any suggestions?
