This is a link to a scoliosis support site where a discussion was started about syringomyelia in cavaliers back in 2005.It was my first time hearing about this and it's amazing that the same questions are still being asked today.
ther replies were as follows
Wow, Kayla! The poor dogs. I wonder if they will continue to breed these dogs knowing the high risk of this condition?
I've no doubt at all that they will, considering that for example Alsatians have been deliberately bred to walk hunched up, and there seems to be a stubborn refusal to test and stop breeding from ones with hip dysplasia. Pug faced cats and dogs continue to be bred as well, despite the potential for breathing difficulties.
I have a pug!... are you saying that is a bad thing?
There's nothing wrong with pug faced dogs and cats, and many are perfectly healthy. What I don't like is the fact that breeders will persist in breeding animals which have serious health problems in order to get a look that they want - like the alsatians. Many alsatians *don't* suffer hip dysplasia, and many pugs don't suffer breathing difficulties, so it's not as though the looks aren't achievable without health problems. I just don't approve of breeding sick animals simply so they match a set of criteria for their looks. Also, some breeders are just odd - I knew a person who got brother and sister persians to breed (to each other? never sure about that), both of whom had serious health issues including faces so flattened that their lower jaws jutted out so that they had trouble even eating. Hope that clarifies what I mean a bit more, I'm not saying that keeping pugs is wrong.
