I am new to this forum. I have two Cavaliers and they are an absolute joy in my life. Maggie is a black and tan 5 year old female, and Emma is a Blenheim 2 year old. They are as different as night and day. The reason I am here is to seek guidance for what my vet thinks is MVD. Maggie was going to have her teeth cleaned today. Before the procedure, my vet did a quick physical exam only to find a heart murmur that wasn't there 7 months ago. The murmur is a level 3. I am fortunate to live 20 minutes from the NCSU Vet School. Maggie will be seeing a cardiologist as soon as my vet can get me an appointment. If anyone has any advice for a very sad mom, I would love to hear it. Thanks
