I just took my 11 week old puppy, Jack, to the vet and I got some insane news...the vet said he has an extra heart beat every so often, saying it wasn't that bad or that loud, which was good, and it could go away after time. But I am still left here wondering why? how will this affect my BABY? can he live a normal life? will he die young? Any advice/input would be appreciated/
