My chin gave birth to two stillborns this weekend, so I took her to the vet and the radiograph showed an enlarged heart and the vet said she has a heart murmur as well. I was wondering if any of you have had a similar experience with the heart issue, what you went through, and if your chin was on any medications. Also, I was wondering if this is a common issue and if it really isn't as bad as I think it is. Thank you very much!
