Hi,
Cheviot - "but the incidence of HD in collies that actually work stock is very low" - is that a personal observation or can it be proved?
It is a personal observation, I don't think it can be proved, as hip scoring in ISDS collies is very rarely carried out, it is only really in the last few years that more ISDS people are doing it, but only because, if they want to sell puppies and dogs abroad, most of the overseas breed societies require it to be done before they will allow the dogs to be registered with their societies. I personally only know of one ISDS dog that was diagnosed with hip dyspaysia, but I do believe, that there is a lot of truth in what Sally says.
I'm wondering why the KC stipulate hip testing as 'required' by their Assured Breeder Scheme rather than just recommended. These Assured Breeders, although they may register dogs with the KC, are quite often working their dogs rather than showing. The AB scheme is not just for show breeders, it is for all breeders who want to register their dogs with the KC. I don't know much about the ISDS (or collies to be honest) so I am also grateful for the information.
It should be noted that Breed Standards were originally written by working owners not show ones.
I really do not know anything about the KC, but the purely KC reg show border collies in general are different, they are breeding them to have short legs! and square heads, usually with a rough coat, and the markings seem to be important features also.
My personal thoughts are as soon as you start to radically alter a breed there are prices to pay, maybe the hips have suffered, in the quest to breed short legged dogs, but I really don't know.
The ISDS do NOT have a breed standard, they are only interested in the working ability of the dog, so ISDS collies come in all shapes, sizes, coat length and colour.
These Assured Breeders, although they may register dogs with the KC, are quite often working their dogs rather than showing.
When you say working, do you mean working livestock, I only ask as I know a lot of breeders and trainers of ISDS collies, and none of them are interested in the KC or becoming assured breeders. I seem to vaugely remember something about the KC holding working tests for dogs, I have no idea what they required in these tests, but a german girl once told me that the KC reg dog she had bought to work sheep would be OK as it had passed it's working test, turned out it had no interest whatsoever in working sheep!
There are however a growing number of ISDS reg dogs also reg with the KC, this I believe is, because quite a number of pups are bought by agility people, and so it is easier for them to be able to compete in the KC affiliated shows,when their dog is already reg with the KC.
