 Before working on the show, the dog "Happy" was a stray that was  abused by her former male owner. Even though she was later rescued  "Happy" still has a fear of men. Before the taping of every new  season Stephen Collins (I) (qv), Barry Watson (I) (qv), and  other adult male actors on the show have to spend some time with  Happy for her to get used to them being around when doing scenes  together.
