Hi we brought our 3 yr old pitbull home just a week and a half ago. He was on antibiotics for his raw paws which we discontinued because his paws were fine and we thought the medicine was making him sick. However he has remained sick. He lays around and sleeps all day, will not play, will not eat and rarely drinks, and he pukes about twice a day. My husband thinks that it is not a big deal and he is still adjusting to this new home but I'm nervous. How can I get him to eat?!
