A black panther or white tiger (or both! lol) white diamond collars and leashes, which have wierd mind-reading protective instincts (al la the Rottweiller in the Omen

) that freak the crap out of everyone else but are as tame as a kitten with me LOL
Alternatively, a cute cuddly white seal, dolphin or giant panda or.....an Apatosaurus! lol
