@Janneke:
Yes, I agree, but that's more important for the one selling the dog than for the buyer right? (if buyer is not puppymill himself.. I mean an educated buyer, who will neuter the dog)
Well, I don't know for whom it is more or less important….but for the breed in general, it is important that all intact dogs that might be bred are tested...IMO
In many parts of the US you can never assume that someone *will neuter a dog, even if they signed a contract saying that they will. So, if I was selling an adult, or older puppy I would absolutely have it neutered before placing...that way there is no possibility that it doesn't get done.
