These are my thoughts at the time I am writing.
And, of course, it is named after the ruler of the underworld in Roman mythology -- just like the cartoon dog.
Actually, I could be off-base on that. The Wikipedia article on Pluto the Dog states:"Several months had passed between the naming of what was believed to be the ninth planet, Pluto, on March 24, 1930, and the attachment of that name to the dog character.  Although it has been claimed that Disney named the dog after the planet, rather than after the mythical god of the underworld, this has not been verified. Disney animator Ben Sharpsteen said 'We thought the name [Rover] was too common, so we had to look for something else. ... We changed it to Pluto the Pup ... but I don't honestly remember why.' Venetia Burney (later Venetia Phair), who as an eleven-year-old British schoolgirl had suggested the name Pluto for the planet, remarked in 2006: 'The name had nothing to do with the Disney cartoon. Mickey Mouse's dog was named after the planet, not the other way around.'
So can Pluto the Dog hunt?
