The BBC Special which aired what was it 4 years ago or so? It is rather old news, how-ever as a result of this special, the Kennel Club in Britain, undertook a full Standard review of every breed standard. A massive job. Working together with the National Breed Clubs, almost every single standard was revised.
In my opinion they did not go far enough, but at least a good step in the right direction.
I would like to point out, there was much criticism of that special, because of its very slanted nature. Having said that, there were obvious points of faults, and yes on the show breeders. There are bad breeders out there unfortunately.
The problem how-ever is rife and a huge concern from the commercial breeders, the puppymills, and the 40million dogs that supposedly come from family and friends pets being bred. Source APPA last year survey. None of those folks do any genetic or pre breeding screening, with perhaps the commercial breeders screen for brucellosis.
The GSD is often times referred to in these types of threads. I admit I haven't watched the herding group too often, or seen the breed in the ring that much, but I will if I have time look up some recent shows on line that shows that breed being judged.
The few I have seen in recent years hands down, are much better configured than say 10 years ago.
And if folks are going to get a mixed breed puppy for sure it is buyer beware. There are not nearly enough studies for any-one to say confidentally that mixes as a group or individual mixes are healthier.
And as yet another reminder there are relatively few genetic tests available for every breed. There are how-ever many pre breeding screening tests we do do!
And as a purchaser if you wish to "insist" on genetic testing, know which ones are there for the breed you wish to purchase, and a general idea of the incident rate within that breed.
Know what are the screening tests the whole array of them, know what the
www.ytca.org recommends, and ask why your breeder has not Chic'd their dog. Not many breeders have for YT's.
