What is a dog breeder? The definition can be interpreted in many ways by different people. A person who owns a dog and allows it to become impregnated or impregnates another dog is NOT a breeder. That person is perhaps an irresponsible owner. Certainly accidents do happen, but if you do not have a well bred purebred dog that is an excellent representative of its breed and who possess excellent health, temperament, conformation and has been cleared of disease and genetic predisposition to disease, your dog should be spayed or neutered.
A breeder breeds to better his breed. Top AKC show dog Breeders of Merit” spend tens of thousands of dollars checking the health, genetics and myriad other factors prior to breeding a litter. Other purebred dog breeders from various countries do the same in order to improve the physical, behavioral, health and compatibility with other animals and humans. Each breed is bred with a specific purpose in mind. Breeders painstakingly nick, or study parentage, carefully breeding a superior dog to a superior bitch. Their entire goal is to improve the breed they love. Someone who breeds dogs for money, and not for the love of the breed and qualities possessed by that breed, is nothing more than a small-scale puppy mill; oftentimes breeding females over and over every heat cycle (approx. every 6 months) without regard to what quality or characteristics the dogs possess.
Any legitimate show breeder will sell a puppy on what is called a spay/neuter or “Pet Contract” if the puppy is not intended to be a show dog. This means that the breeder felt that the dog should not be bred.
Perhaps your dog is very straight in it’s hindquarters conformation. You might say, “Who cares? I’m not going to show him.” But did you know a dog who has a very straight hind end will be more likely to get arthritis or patella subluxation . This can result in pain and a very early demise to your dog as well as tens of thousands of dollars in surgery, after care and physical therapy. Remember that any time we are combing DNA, there are no guarantees. But when we combine the DNA of two healthy, well conformed and behaviorally sound individuals, we have a far greater chance of having the progeny also with good health, conformation and behavior. So yes, it DOES matter.
