depends on your definition of dog breeder, there are people who are very consciencious about how they breed, how often,
and the quality of the pups. Then there are people who buy a bitch, breed her at the first chance, and every chance after, and are just marketing puppies.
I've bought both types of dog, my chocolate lab was from a breeder who was very serious, he was intact, but my purchase papers expressly forbid using him to breed. And my price ($1500) reflected that. His siblings sold for over $2500 each.
