My yorkie Isabella, has been having a bit of stomach trouble. She always seems to be burping, before she eats, and after. She burps as though she is about to throw up... but does not throw up. She vomits occasionally, the vet says she has a very sensitive stomach. We have been to the vet, and emergency room for this many times, and the vet always says it is due to her extremely sensitive stomach. She has also been wheezing a bit more that usual, and occasionally takes long deep breathes when she is relaxing. Do you think one has to do with another...or am I just overreacting? We feed her a soft food, from Merrick (called Wingalings-de-boned) and Spot Stew. Maybe it is just her food and she needs a food that is more plain? Has anyone else had this situation with their yorkie having a sensitive stomach? Thanks
