> it showed CKCS having seizures because their skulls were too small, and the way that Bulldogs are being bred with shorter and shorter snouts, sharpei's being bred to have more and more wrinkles.
Actually I have been around in dogs since the last breed came into the UK and the improvement and reduction in loud breathing and wrinkle has been amazing in just 20 years. Though casual back yard/commercial breeders will breed from anything and the public like the wrinklier the better.
Bulldog breeders have been moving toward less exaggeration, and conscientious Cavalier breeders are now MRI scanning (but this doesn't guarantee freedom of problems, it's just an indication). Of course changes take time, took time to get this way almost unnoticed, and will take just as long to reverse the trends.
Considering that they have been trying to tackle the biggest problem in the breed, heart troubles, is it any wonder that they have stumbled into this issue more, they re not alone the very act of miniaturisation has given rise to a tendency (the skulls aren't too small per se, but there is a narrowing causing pressure in some dogs).
You can bet none of the puppy farmers or casual breeders where this breed is a firm favourite bother with any health testing, (yet even there the breed overweight, with dicky tickers manage to live a long life) but the show side where it is easy to trace things gets the blame, and the impression is that the breed has gone to the edge of viability/extinction, patently untrue.
When there is no clear -pattern of inheritance or even a definitive diagnosis technique (lets face it the average vet doesn't have an MRI scanner), issues can remain hidden until the incidence becomes significant. Also this issue is not confined to this bred or even just toy breeds, so not really anything to do with a small skull (after all Cavaliers are one of the largest of the toy breeds).
I too have a natural and healthy breed. The only eye condition we were tested for was PRA and we had extremely low incidence, but we finally got a DNA test and so many were found to be carriers, the only reason incidence of affecteds was so low as it is a late onset condition (some dogs don't live long enough to go blind, even at 15), and because most individuals would not sire many litters, or have many litters, so the chance of two carriers meeting is less. We have had cases of Glaucoma, sadly open angle so no way of testing for it, and not enough cases to prove inheritacne one way or another, so we aren't even on the under investigation schedule of the eye scheme.
If we take any sensationalist journalism we would believe that the country is full of wife beaters, child molesters and that care homes mistreat the elderly on mass. Sadly these things happen but are a small percentage.
