I agree with YorkieRose and MyFairLacy.
It really depends on what the breeder does to correct the situation and what testing was done before breeding.
If a family wants to breed their healthy pets, I have no problem with that (I know some people do, but I don't...it's their right to breed if they want to). My problem is when they want their cute dogs to have puppies and then want to sell them. So the dogs are probably not standard and they haven't been health screened. If these people want to breed their family pet and it doesn't meet the standard or hasn't been health screened, then they should keep the puppies and then they can pay the vet bills later. It isn't fair to the dogs or to the new owners to not do everything in their power to make sure the dogs are healthy pre breeding.
My opinion only...
