The cavalier breed at a cross-road
Could I mention this from the Veterinary Paper ,PREVALANCE OF ASYMPTOMATIC SYRINGOMYELIA IN CAVALIER KING CHARLES SPANIELS.
"The High Lifetime Prevalence of Syringomyelia raises concerns for the Welfare of the CKCS Breed and also suggests that Eliminating the Genetic Risk Factors for the Disease by Selective Breeding may be difficult ,because the Heritability has been shown to be Complex(Lewis and Others 2010 and the Prevalence of the Determinant Genes within the Population is therefore likely to be High
The True Prevalence of Syringomyelia in the General CKCS Population is expected to be Higher than that found in the Sample Population because Symptomatic Dogs were specifically excluded"
Has there now to be other Options considered since this is a Complex Condition Genetically ,that there could be several or many Genes involved and as yet there are no NO DNA Tests as yet for a Complex Condition.
That some of those Pet Cavaliers Bred might have no SM Genes ,since many of the Show Bred Cavaliers often go back to to the same Cavaliers ,or the thought of Out-Crossing to be being considered .
For the Survival of our Cavaliers has the time come for some of those Options to be being explored.
Since the SM problem is so Rife in the Cavalier Breed will Selctive Breeding be Perpetuating the SM Problem,I know these comments will be unacceptible to some ,but what is the answer.
