On Saturday my husband took Chili to the vet to get his shots but he has also been gagging/coughing and it wasn't getting any better (we had taken him to the vet already for this twice) so I had my husband ask if it was a collapsing trachea. Well it turns out that when the vet did the X-ray to look at his trachea (it's fine) he noticed that Chili has an enlarged heart and a heart murmur that the vet said he could barely hear. The vet gave my husband antibiotics for Chili and sent him on his way. My husband didn't ask a single question
. Do any of you have any experience with this? What are the antibiotics supposed to do? He doesn't have any other symptoms besides the wretching cough. From what I've read so far this is a death sentence and my heart is totally breaking. Is there any hope for my puppy?
