I started feeding my32 pound dog raw 2 weeks ago, ground beef mixed with 5% liver, 5%heart and kidney mixed. I have been feeding him 4 ounces am and pm and he loves the food. I notice that if he drinks too much water after he eats that he vomits it up about an hour later. I have been giving him just a little bit of water to drink after he eats and he only spits it up a little bit but not much. Should I mix some water in with the food? Maybe his stomach is still getting use to the raw food?
