I hope it's OK starting this as a New Thread,.
I contacted Dr Helmuth Wachtel in Austria to-day about the In-Breeding in our Cavalier Breed. I had been involved with him a number of years ago ,when he was comparing the Pedigrees of the British Cavaliers with MVD with those Cavaliers' Pedigrees in Austria with the same Problem .
At that time he replied to me ,saying that he was convinced that the In- Breeding in Cavaliers had caused their MVD Problem.
I had asked him to-day ,what were his views about the In-Breeding in Cavaliers ,and giving him the details about it in the 30's and 40's etc.
Here's his Reply.
To attain New conformation needs More line/In-breeding
Dog Breeds are a Cultural Heritage and should not be subjected to such changes
If Population Genetics would have known Earlier .
A Breeding System such has the Present One would not have been possible
In -Breeding and Line Breeding leads to loss of Genetic Diversity ,meaning lacking tools to keep an Organism Healthy,Vital and Enduring owning to many Genes(Allele) providing Enzymes and Proteins that are tools for that Goal.
Loss of Diversity produces Short Life-Spans ,Increased Infections ,and often Horrible Inherited Diseases .
Mrs A. Pitt, the Founder of the Cavalier Breed ,were her comments made in 1957 also slighter later, that the Cavalier Breeders in those early days of the Cavalier Breed ,were Breeding Cavaliers with no thought as to the Future of the CavalierBreed,had this information maybe been learned from her Father ,who was a Geneticist.
