My 9 year old toy poodle started vomitting more frequently, 2 to 3 times a week, a few months ago. I tried home remedies, zantac, pepto, tums...nothing seemed to help. She would continue to vomit a foul smelling yellow liquid while i was at work, or even in the middle of the night. The vet i took her to immediately opened her up saying she had a blockage. There was nothing. I think this vet may have been knife happy. Still, a week and a half after surgery, my dog continues to vomit yellow liquid. Her blood work was "perfect" according to this vet, and she behaves like a normal happy poodle should...she just barfs a lot. What should I do? What do you think this could be?
