Cotton dog is NOT in heart failure!!! He has an enlarged heart and a murmur, but it has not yet progressed to the point that we need to worry.
The problem is with his trachea, which is irritating his throat and causing excessive coughing. So, we increase his cough inhibitors, and keep a close eye to make sure it doesn't get worse. In the meantime, all signs indicate that he could be a happy, healthy little dog for a good while yet.
You can't see this, but I have a huge, stupid smile on my face. I am very happy to hear this news!
