puppy with grade 2-3 heart murmur...
I came across a breeder with a puppy which she said have a grade 2-3 murmur. I'm wondering, will the murmur fade away as the puppy grows or it will become worst?

Some Cavaliers have a puppy heart murmur that will disappear as they grow older. Others, of course, have the ordinary MVD murmur, but this normally starts as a grade 1 and gets worse gradually, rather than being grade 2-3 while still a puppy, which is quite unusual - unless of course there is some other complication affecting the heart.
