Patch it Up, or Toss it Out?
There are major problems in dog breeding.
There are puppies being sold with genetic diseases.
Puppies are being bred for one purpose but sold for another - bred for the ring, but sold as family pets.
Health and temperament are often NOT priorities with show dog breeders.
The person producing the puppies (the dog breeder) is often trying to produce traits which the buyers (puppy owners) don't want, or don't care about.
While traits that the family buying the puppy want their puppy to have, are often traits that the dog breeder doesn't want or care about.
Genetic variation is being lost very rapidly. Some of it can never be recovered even if we could stop the inbreeding, and popular sire trends right now. There is no recycle bin for genes, once a gene is extinct, it is gone forever.
There are puppy mills, and smaller scale puppy mills: basement-puppy mills, garage-puppy mills, and extra-bedroom puppy mills, where dogs are kept in crates or cages. It is cruel to the dogs, and often produces inferior puppies that are not bred to be good pets.
Salon agriculture?
There are people breeding purebred dogs who don't even like dogs. They breed a few litters, so that they can claim to be in the business of selling puppies, so that they can use their dogs as a tax shelter. They can be a bossy and very vocal group, trying to get the rules changed into their favor.
Real puppy farmers?
Covered that, under puppymills. That is what for profit breeding often is.
Hobbyist?
On their own, hobby breeders might not be too bad. But they tend to get social, and led around by craftier people who are using dogs as a tax shelter, selling dog related services, using dogs as sport objects, or using dogs in experimental research or product testing.
Dr. Frankenhound?
That bunchers get dogs and sell them into research labs (laboratories), and product testing centers is a fact. It is a business. Pets do get used this way - it can be torture.
Some breeders produce puppies with genetic diseases to sell into research. But many of these puppies end up being sold into pet homes, or to other dog breeders.
Competitive Sports Breeder?
They only want the few puppies that are most likely to win in the ring or in the field. Their left-overs are taking over other areas of dogs, like kudzu in a southern summer. Like someone who breeds fancy carp, and sets the not-fancy-enough carp loose in public waters.
Family Pet Owner?
Pet puppies traditionally have come from other people's pets. A neighbor's dog has a litter of mutt puppies, and one of your kids asks "Can we have one?". This seems to be the best way to produce pet puppies.
It is often best that ranchers produce sheepdogs, that mushers produce sled dogs, that hunters produce hunting dogs, that pet owners produce pet puppies.
Two things have messed up this traditional method of producing puppies.
1. The pet market is the largest demand for puppies. Commercial breeders have pushed the pet owners out of their own turf. Pet owners are too naive, and the business people too organised.
2. Some uses for dogs, produce a large unwanted surplus of puppies.
Competitive events, like dogs shows, means that only those puppies most likely to win in the ring, have any value to the show breeders - the rest of the show-bred puppies will not find a home with a show dog person.
So the left over puppies are sold as pets, or as "pet quality", although there were not bred to be good pets. The traits selected for were NOT: how good they are with children, how easy they are to house-train, if they can be left in the house without destroying it, if they don't bark all day, and if they have a desire to please.
Other competitive events have a similar effect. Only the most likely to win puppies have value to their breeder - the rest are sold as pets. This includes breeding fighting dogs: the puppies that are not quite "game" enough, or not "game" at all, are sold as pets.
