My 8 month old pitbull has been vomiting, and its mostly yellow mucus texture. He won't eat and he barley drinks water. He drank water last night arpund 8 then I gave him white rice at 9 pm then at 4 am he threw it up. He always finds things and takes them in the backyard and chews them I have found small pieces of plastic in his poop before. Worried he has something stuck somewhere in him, where is it and what can I do? I did set an appointment but I'm on a low income and I am worried its going to be an amount I can't afford. HELP!
