Peanut

Peanut is the pet dog of Beth and Kirk Sutherland.

When Kirk learned that his wife Beth had committed bigamy when she married him, he left her. He was later upset over the death of his sister Maria's dog Ozzy, so Beth and her son Craig hatched a plan to win him back by getting him a puppy. Kirk initially rejected Beth's offer, but changed his mind later that day after admitting that he missed Beth and had a weakness for dogs.
