You can check your dogs pedigree for health testing via the MYKC site or the KC main site, I wouldn't buy a puppy that didn't have a whole pedigree of hip scores & at least 5 generations of eye testing, plus both parents having been fully DNA tested

Both parents were fully DNA tested and I have copies of all the results, plus, as I said, I trust Jack's breeder implicitly and know she wouldn't have taken on a bitch without going into her background methodically.

Having shown Jack's pedigree to a border collie breed judge, who pronounced it 'lovely, lovely breeding', that was good enough for me (who really isn't into breeding at all but just wants a pet first and an agility dog second!).

The health tests of ISDS dogs do not feature on the KC site and the Gwynion dogs are all ISDS.

Yes, I thought that at first sight too. I saw too many dogs and too many different breeds, as well as cross breeds.

"Supply" makes me think that they are just another business churning out untested puppies for more or less... modest prices.
