I have just had word back from one of the Researchers in Denmark into the MVD Problem in our Cavalier Breed.
The Inheritance of MVD is most likely Polygenic ,this means as was explained to me ,that there are several Genes involved .
It was also mentioned that it would be very nice to get a better idea about Inheritance ,however ,that would require very detailed Clinical Information on a Large Number of Animals
The Researcher said that with the Tools they have at Hand noe ,it is easier to look for the Genes underlying the Disease.
I had asked about the Heart Problem being known about in the 1940's -50's etc in Cavaliers
and that Cavaliers were being exported from Britain, from the 1950's, her answer was , the Disease might very well go as far back as the 1940's and most likely all Cavaliers around the World with the Disease carry the same Mutations.
Those Mutations have to be found ,then the information could ensure an Improvement in the Problem,
Now, we do know that the Cavalier Heart Problem has been in Cavaliers for at least 60 years,but what about the Cavaliers' SM Problem,it has appeared in so many other Countries, but when was it first seen, I think it's been mentioned here in Britain in the early 1980's, is it like the MVD Problem, are the Cavaliers World Wide carrying the same Mutations.
Hopefully the SM Research in Canada will discover this, but in the meantime ,it has to be upto the Cavalier Breeders to have Health Tests carried out on their Breeding Stock for both those Two Conditions.
If Cavalier Breeders won't co-operate in doing this ,then will Mandatory Health Testing be the only answer for the Future of Cavaliers.
Some Cavalier Breeders have claimed about being in the Cavalier Breed for 30 plus years, so what have they been doing wrong to have allowed the Cavalier Breed be in the mess it's in to-day.
