When I had Teddy in for his second set of boosters, my vet said he had a small heart murmur, but not to worry about it yet - it could just be a puppy murmur that will resolve itself. I've been reading that puppy murmurs can go away between 3 to 6 months of age, but wanted to see if any of you had experienced this problem and what happened, and if the murmur did go away, by what age?

Thanks for any input, love my little boy to pieces and trying not to worry too much at this early stage.
