Jonesy The Dog

Jonesy, also referred to as 'that damn dog ' by officers who are allergic to the little guy, is a dog kept aboard the ISS Serenity. The dog's official purpose is to control prisoners aboard the ship, but being a dog, he is incompetent and doesn't realise that. Due to this, he spends most of his time hiding to the point where some people aboard the Serenity question if he even exists.

Some say that Jonesy is not actually a dog, but is instead a small bilingual cat that looks like a dog, and speaks like a dog. This is, of course, false.
