Personally I don't think anyone should be breeding unless it's to improve the breed. Reputable breeders don't breed often (1-2 litters per year) And work to improve the health and temperament of their breed. The dogs are also sold with spay and neuter contracts to responsible people who aren't likely to give the dog up. If they do have to rehome the dog, it's in the contract that the dog has to go back to the breeder. While I do agree with rescuing whenever possible...Some people want or need a dog that has a solid foundation (Breeding)
