S1·E4 It's a Dog's Life

Lucy finds an injured dog, which she names Dennis, and starts nursing it back to health. Mel disapproves, warning Brian that Lucy will be upset when it dies. Meanwhile, Josh spends the money he raised for a charity event on a football ticket, and starts to earn the money back by putting up 'dog found' posters for Mel. When Lucy finds out, she pays him even more to bring them all back again, by which time Mel has warmed to Dennis and agrees to keep him. However, Josh returns with a 'Have you seen Woolly?' poster and Lucy and Mel realize that Dennis, a.k.a. Woolly, needs to go home to the people who are missing him.
