You still have no right to breed it. Now you are a backyard breeder with the purpose of breeding pups for bucks. You are a backyard breeder. Backyard breeders sell pups that aren't up to the standard of the breed. They do this for many reasons.
None are good enough reasons to contribute to the killing of dogs.
Backyard breeders will swear all of their pups went to a good home. Some may have been lucky enough to go to a good home but more than half of them will end up dead, in a shelter, alone, on a cold table with a needle sticking out of their leg. Some of those good homes will get tired of the dog and they will just give it away to anyone who is willing to take it. Some of your beloved dog's children will end up living alone in a backyard, barking all night, cold and neglected until the owner gets complaints and then that pups will be dead. Some will be starved and beaten.
