Gus, Abbey, and Vinnie
Legendary Tonight Show sidekick Ed McMahon rescued a wheaten terrier named Gus. He can be sweet and cuddly around Ed's family, but he has become seriously aggressive toward Ed's assistants and guests. Next, meet the Swanson family, who live outside Minneapolis, Minn. They adopted a beagle named Abbey who now won't leave the house. Then, in Torrance, Calif., meet an Australian shepherd named Vinnie who is so territorial of his owner's house that no one has visited in two years.
