My 6 month old tea cup yorkie has been throwing up yellow foamy stuff. He won't eat or drink anything. He is very sad and won't move from one place he will only get up when he needs to vomit. He has been peeing and he also has diharrea. The only thing I have been giving him is pedialyte. Unfortunaly, we are unable to take him to the vet. I am very worried and would like to know what I should do to make him feel better.
