Dog is lethargic and pukes food up as soon as he swallows it.
My 5 month old Yorkie was fine until I gave him a dog treat a few nights ago. He seemed to be choking on it because he gagged and yelled and finally puked some of the treat up. He went for another day without eating or drinking and became lethargic. I took him to the vet the next morning and he said Max had a high fever and probably had an infection so he gave him ammoxicillan. 5 hours later I took him to another vet because he began gagging and puking up food again as soon as he swallowed it. She did blood work and everything came back fine but we still don't know what's wrong with him. I can't keep his medicine or food down him even though I gave him only a plain cooked potato which the dr told me to do. Neither dr seems to know what's wrong with him and I don't know what else to do. He's only 4 lbs and hasn't eaten in over 3 days.
