Our friend has a 5 month old Shih Tzu puppy, that has a heart murmur. They just found out today. The puppy also has two genetic eye diseases. How serious is a heart murmur in a puppy this young? And how do you fix this and how much does it cost? And does the puppy need to go to a specialist? Please answer as quick as you can! Thanks!
Shelties: Not enough words to describe how much I love them.
