I have an ex-stud dog.
He wasn't from what you'd call a 'normal' breeder, but from a Welsh puppy farm. He'd never seen a bird in the sky when we adopted him.
He's still traumatised 2 years on, but I wouldn't change the experience for the whole world.
Just bear in mind there are several types of breeders and think about what you are willing to take on. I don't tend to trust breeders that advertise in newspapers, but that may be a generalisation - it usually makes me think puppy farmers or backyard breeders. I have adopted dogs from both these backgrounds and I can't describe the contempt I have for these people.
