If he's like most Labs, (like mine!) he's a chow hound and wolfs down his food. How many times does Hooch eat per day...1, 2, 3? You might try feeding him smaller amounts spread out over the day. But I'd really suggest you consult your vet. He may have a reflux problem, which would cause him to throw up his food VERY shortly after eating. There are a few medications (Reglan is one) that helps to relax the GI tract and might help. Is he pooping ok, drinking enough water? Has he shown any other signs of illness like lack of energy, change in temperament? I think a quick check up at the vets will help to ease your mind and get to the cause of it! Keep us updated and hugs to Hooch! Feel better soon! Sandra
