Even if it's not the case with your pups, that they get good homes, you are taking away those good homes from the homeless animals. Breeding because you want to is no reason to breed. Please spay and neuter your dogs. Hundreds of dogs in my county alone are killed every month because no one could give them a home. Because of the irresponsibility of people just like yourself. Please reconsider breeding and read this page.

Sorry if I'm coming on strong but this is something I'm very passionate about.
