The original puppy mills show drew a huge response. The topic generated thousands of e-mails and comments on Oprah.com's message boards.
Kathleen wrote, "While I appreciate your exposé on puppy mills, I found the lack of support for reputable responsible breeders very sad. We are all now painted with the same brush."
Oprah disagrees. "There are a lot of wonderful breeders out there and obviously because you wanted to write me, you must be among them," she says. "And so I just ask people to be more thoughtful and responsible when you're buying your pets. ... But as we were saying earlier in this show, there are 8 million dogs in shelters. Many of them purebred dogs. And so I've been encouraging people to go to the shelters. But if you want a purebred dog and know of a great breeder we welcome your support of the breeders also."

Oprah has one more word on pets. "Remember," she says, "one of the best things you can do for your pet is spay or neuter."
