Hairy and Sweet Pea were brought to Shelter 17 together, fighting with each other as they were brought in. Hairy explained to Squirt and Niblet that he had been sitting outside a meat store when he saw Officer Ketchum. He tried to warn Sweet Pea (Who was lying on a couch next door) to join him in the garbage can to avoid detection. Sweet Pea refused, and Hairy fell out of the can, forcing him to hide in Sweet Pea's sofa, (to her disgust) which failed to keep Ketchum from taking them.
Hairy's perfect person, Leo, was soon found, and Squirt and Niblet took him to his house. However, Hairy learned that Sweet Pea's perfect person was Leo's sister, Ruby, meaning they would have to live together. The two kept up their feud, which led to their owners fighting each other. As Hairy and Sweet Pea fought, they ended up on a tennis table that rolled down into the sewers. The two were forced to work together to get out, gaining a new respect for each other in the process. When they saw their owners losing a table tennis contest, they went over to them, bouncing a tennis ball between their noses in order to remind them to work together, inspiring them to win the contest.
