When Dogs Learn New Tricks

Bill and Oprah are joined by H.B., a Pomeranian rescued by Main Line Animal Rescue from a puppy mill in Lancaster County, Pennsylvania.

Bill says dogs like H.B. are the reason laws need to be changed. "He had his leg cut off with a pair of tin snips," he says. "He got his leg caught on the wire flooring of his rabbit hutch. Most of these animals are kept in rabbit hutches and stacked. A dog below him grabbed his leg and it became swollen and the farmer, instead of cutting the wire, he cut his leg off. And that's typical. ... He's also missing an ear, probably from a dog fight because he was in a cage with another 12 dogs. He's the sweetest thing in the world."
