I just came across this documentary from the BBC in the UK....The film is a disturbing and sad film concerning the dramatically declining health and the wide spread genetic problems that are putting dogs in jeopardy of extinction.....
The show breeders are refusing to acknowledge that a problem exists and they will purposely breed dogs with genetic issues because the breed clubs are refusing to change their breed standards. The breed clubs are most concerned with looks and beauty than health or genetics and will encourage inline breeding to get the desired look.
I was so disturbed to see a Ridgeback breeder openly admit that even though a ridge back is a deformity they will breed for it and will kill the healthy pups that don't carry the ridge.

Equally disturbing is the Caviler King breeders breeding their dogs with a genetic brain defect in which the brain can not fit inside the skull......And Danny the Pekineses that has a genetic disease and they continue to breed him because he won Crufts....All this breeding is being done by show breeders for beauty. So, so sad and disturbing.....Click on the blue band on top of the box if you care to see the film.....
