Hi Bet and welcome back.
My sister lost her nine year old cavalier to MVD about a month ago.Thankfully she didn't suffer and went quickly but left them very traumatised and suffering massive guilt that they couldn't/didn't do more.
I read Simon Swift's report and wasn't sure what to make of it,although it was only a summary.
As for PDE only giving him a fraction of the recorded time to talk about the Club heart scheme,it allowed Jeff Sampson instead to fly the flag for the scheme which he did quite robustly.
I think many breeders have done very well in improving MVD,maybe they just need to get them tested regularly and recorded on the heart list.
The list just seems to be *over fives* but the dogs could be any age.
The most depressing fact is the acceptance of the veterinary profession of MVD in the breed.My own vet just calls it the "breed standard murmur".
There are many people who are unhappy with things in the doggieworld,some complain and do nothing,others just blunder along and go with the flow but every now and again a few will come along and decide they can either wait for someone else to do something or get off their backsides and do something about it themselves.
It's always good to see a pet owner battling for the breed they love so much.Hope you've been keeping well.
