Nope they are in the puppy trade or business of breedign and selling dogs, not the same as a breeder that is a custodian of their chosen breed.
Nothing ilegal and never will be as it would be seen as an unfair restrictin on trade.
the latest bill about the breeding and welfare of dogs actually does not allow licensed breedrs to sell pups under 8 weeks, EXCEPT to licensed Pet shops. How bad is that. You can guarentee the puppy farmers woudl much rather sell tiny pups wholesale to a dealer than have individual pet buyers scrutinising hter facilities to buy pups over 8 weeks old. If they do it is likely they will ahve the pusp the dealer didn't want, perhaps defective in some way.
