I have an 11 week old puppy we have had for 3 days now. He ate the first day we brought him home but then vomited 2 hours later. Now he does not won't to eat or drink anything he just lays there n stares at me, I'm worryed there is something wrong with him. He tried to eat a little bit last night but then vomited that up as well. He seems so dpressed I need advice.
