If you have pedigrees on two dogs showing nothing but impressive titles going back at least the last seven generations, and you acquire a puppy from each of these lines and decide not to show them for personal reasons, ie, no time, no money, believe a lot of titles are “bought”, just not interested, etc.
If those puppies still conform very accurately to the standard, have excellent temperaments, and have had all availability health screenings, with excellent results,
Then why does breeding them make you a horrible person and a “BYB”?
Honestly, if you don't have money to show or compete with your dogs ever
, then you probably don't have money to breed or raise a litter when it comes to Dobermans. Health tests, stud fees, and then the costs of actually raising the litter are quite high.
And that's assuming you get off easy with a smooth labor and delivery, which is not always the case. C-sections aren't cheap in Dobermans either (or in any other breed that I'm aware of).
However, I'll bite on the rest of it.
It doesn't make you a horrible person and a BYB if it happens every now and then. Sometimes, good breeders have dogs that they don't title for various reasons here and there. But I'd say it's definitely a red flag if its standard operating procedure to acquire dogs and never compete or title them but breed and breed and breed.
One reason is kennel blindness. How do you know if your dogs conform to the standard if you're never having them evaluated by an impartial but knowledgeable party? And if you're never getting out and seeing other dogs firsthand and putting your hands on them?
Another reason is limiting your own knowledge and experience when you never train or compete. How do you know the depth and breadth of temperament(s) you're producing if you never train, compete, and title?
Really, if all one does is obtain dogs and breed them, the only thing anyone can be absolutely certain of is the fertility of the dogs.
There are plenty people who will give you money because you have fertile dogs and you let them hump twice per year but that doesn't earn you the label of a "good breeder" and it certainly doesn't set you in the ranks or company of those individuals who do health test, work, and title their dogs.
