There may be legitimate and good reasons for certain types of dog breeding, but I can't think of any. I saw a news clip last night regarding 'backyard breeders'. It upset me to see the conditions in which these animals were kept but that's only part of the issue. The real problem, in my mind, are the people who insist in buying bred animals.
WTF!?! There is always an over population of pets at local animal shelters. Good animals that need homes, but these people insist on having a specific breed or some dumb shit like that. Come on people, do something good with your money. You can adopt a shelter dog for a lot less and then if you insist on spending that $1000 anyway, give it to the shelter to help them continue the good work they are doing.
If people stopped buying those, literally, retarded toy dogs, then breeders, especially backyard breeders, would no longer have incentive to breed.
The news article goes into requiring licenses and such and I think that would help, but at the end of the day until the buyers stop, the breeders will keep supplying.
Rescue an animal for crying out loud!

Hell just Google "Dog rescue" or "Animal Shelter" and you'll find many many links to all kinds of organizations that will help you find a companion. They are happy, you are happy and you've saved an animal!
