I think Tipper's heart enlargement is due to the breathing difficulty and it is putting more stress on her heart. There are no specialists we live in the country. I am however having the vet look up xrays of Tippers chest and trachea from a few years ago to compare them. I do not always trust his judgement, as he has steered me wrong before, so that is why I am out here searching for help again. I am hesitant on putting her on Bronchodialators as she is allergic to everything. I need to find a solution to ease her breathing and fast, before anything else happens. Of course my Vet has been off since Friday and comes back Tuesday so I have to wait until tomorrow. Thank you for the help, I will see what I need to do. The blood test I was referring to tells you if the heart is working properly, then you have to go from there. I researched this online, and that said it was a good indicator of heart problems.
