They are legal, but in reputable breeders views, most disreputable. they basically exist to facilitate the sale of irresponsibly or puppy farmed puppies. the ones who set it up own a big puppy supermartket/pet store in Manchester called DpgsRUs (formerly Mayfield Kenneles) they buy in whole litters from puppy farmers and are the bane of breed and general rescue, as when the impulse buyers get bored, that is where the pups end up, with neither the Puppy supermarket or breeder being interested inpups welfare.
In our breed for sure, and I am sure in others we managed to prove when so called breeders were selling through deelers and as this is against the KC code of ethics they were stopped from registering. It appears that it was much easier to set up their own registry, as the average man in the street assumed registered meant KC registered. Some folk have come unstuck when they wanted to show or breed from their dogs, as in fact their paperwork is no more recognised than that I could produce myself!
They aren't the only one, I think there is another large place in Blackpool that has their own no questions asked registry!
NO DECENT BREEDER WOULD EVER SELL THROUGH A PLACE LIKE THAT no matter how they try to say that they have stock from leading breeders. Repuitable breeders go through a lot of sleepless nights rearing and caring for their carefully planned pups, and agonise about the homes that they go to, so would never contemplate letting one of their precious pups go to someone they had never met and screened for suitability themselves!
Puppies bred in this way require extra socialisation to ensure they make a decent pet, as they may well have not had the sort of rearing environment where they are used to all normal household activities, and may well require extra work geting them good with others of their own kind, as they often leave thir mothers too early.
I would suggest attnding a nice friendly pet obedience class, it really will help you get the most out of your realtionship with your dog, and help ensure a well adjusted dog. the teenage stage is a time when training is particulrly important!! :D
