my sweet cookie got her first exam today. She is 6wks 3 days old. She has 3/6 Left Systolic Heart Murmur. I have researched and I am still not sure what to think. She has has been having a rapid growth spirt. She is a puppy from my Daughters ( Duke and Daisy ) she is still with her mother and litter mates. I will bring her home in a week. Vet said bring her back in 2 weeks, told my daughter not to sell her. These puppies are all loved. They are not being sold, but givien to family and freinds that we know will love them. Could never be a breader, want to keep them all. I’m just so worried about her, in love with her. Any experience with heart murmurs?
