Are you planning on getting your dog titled or anything? Looks like they don't own the bitch from your pup... or maybe it's just not on their website? I'd prefer a breeder that handles their own dogs, but that's preference. I'm still confused about the jump from the breeder to talking about breeding your dog. Also, breeding two titled dogs does not a good breeder make. Don't know if this breeder knows how to match up pedigrees correctly or not... or how much he knows about his own dogs since they aren't HOT. They are gorgeous, though! Do you have pics of your dog you can share? Bet she's a looker, too.
There are so many contradictions in breeding dogs.
A good breeder breeds for the future, but a good breeder has only so many dogs that they can manage on their own. A good breeder will take dogs back if necessary. A good breeder does not put down dogs as soon as they stop producing. Some of you would have a heart attack to think that a breeder might place a retired bitch. If you breed then rescue, if you don't rescue don't breed.
It is easy to see that if you have your foundation bitch and her progeny that are now retired, and some of their progeny who are currently producing, and some youngsters to see how they fill out in order to move forward with, a dog or two that did not turn out, and are now pets, and maybe a rescue or two, you are going to be way over the moon with dogs. Which makes you not a good breeder because you have more than you can properly care for.
Also, SOMEONE has to have stud dogs. Frankly, it makes sense for some breeders to own good stud dogs. But that does not mean that are the best dogs for their own bitches, and it does not mean that they are not a good dog for an outside bitch. If a stud owner breeds his dog to an outside bitch and does this with thought, that breeder may be very interested in the get. They may help to place the puppies and they may have used a stud fee for a puppy.
So a possible answer to the riddle is to place your bitches on a breeding contract, co-own bitches, so that you don't have a dozen or more dogs, and the bitches have a family of their own. I do not see co-owning bitches, breeding contracts, stud-service for a puppy or puppies, and then selling those puppies as a negative at all.
Frankly, I think that it is helpful for a breeder to have trained a dog to some level. But I really don't see it as imperative that they handle and train every dog that they use. If they send a dog out for training, a good breeder will be able to evaluate the dog themselves, they do not necessarily have to walk every yard of the dog's training to gain the proper perception of the dog's ability.
