Today we met Rhett Butler, a loveable large puppy. He weighs 50 pounds, is six months old and "as solid as can be," says Kathy Hodge of the Humane Society of Calloway County. His breed started a discussion involving Staffordshire terrier to a border collie lab mix. He's mostly black with a white stripe on his face and white paws. His foster parent says he tends to be very quiet.
