I hope this is a mistake. I had two vets tell me that Barney had an enlarged heart based on his xrays. I took him to a cardiologist, and when I did she shrugged saying that every yorkie coming in has had their vet say that it's an enlarged heart but it is because their hearts are big and their chest cavity small creating a shadow on xrays. She did an ultrasound, and she was right, he has a normal heart. Barney also coughs up a lung when he runs, and it's allergies and reverse sneezing.

I hope the same is true for your Momo, that his heart is healthy!!

Personally, I would take him to a cardiologist and not do the in-house thing. I would let the cardiologist do all the testing at this point and not waste any more money with the regular vet.
