Well, obviously my dog came to me already neutered. But if he wasn't, I would have had it done ASAP. Many dogs do have health issues that shouldn't be bred into future generations.
Nothing against anyone here, but I think "pet quality" dogs should be fixxed and kept as pets. It's their offspring that end up with massive health problems and/or dying in the shelter.

There is not enough 'GOOD homes' for all the pet quality dogs.
Big difference between breeding your confirmation and best of show winner, and breeding your Golden retreiver/black lab mix with hip problems, just because she is a "good pet".
A good dog breeder will check out potential owners before letting their puppy go to anyone.
A backyard breeder will let their puppy go home with anyone who can pay their asking price and not care what happens to said puppy.
