If you have your heart set on a purebred dog, be prepared to pay! Even "pet quality" purebreds, who aren't up to snuff for the show ring, can go for more than $1,000 depending on the breed. Upscale pet stores may even charge $3,000 or more for a pup. A responsible breeder will: Find out whether you want your dog as a pet or for companionship, working or competing. Provide at least a three-generation pedigree (maybe more) with championship titles. Provide certifications showing the dog's hips, elbows and eyes are free of defects. Ask questions, even getting nosy sometimes. Responsible breeders want to be sure their dogs are only sold to customers who will give them the best possible lives. Require that if a buyer cannot keep a dog any longer, he or she will return the dog to the breeder, who can then be sure it has a good home.
