With training and a focused outlet for his energetic natural drives, Moose started to calm down. After only six months of training, he was cast on Frasier as retired policeman Marty Crane’s dog. Moose had the ability to fix Kelsey Grammer with an unwavering stare, which became a running sight gag on the sitcom. BBC Entertainment reports that when the TV script required Moose to lick one of his co-stars, sardine oil was slathered on the actor where the dog was supposed to lick.
