Plutopia

Plutopia is a Pluto short that was released on May 18, 1951.

Synopsis
Mickey's on vacation at Camp Utopia. At first, Pluto thinks it really is utopia: trees everywhere and a cat to chase. But the cabin rules are strict: no dogs indoors and dogs must be muzzled and leashed. Mickey puts Pluto out to sleep, just out of reach of his food and Milton comes down and taunts him. Pluto falls asleep and dreams of his "Plutopia" with a subservient Milton begging Pluto to bite him and catering to his every need.
