-The Dog (RD: Parallel Universe)
The Dog is an alternate version of The Cat, from the female-orientated parallel universe.
Presumably, The Dog is a descendant of a dog that Deb Lister brought onto her Red Dwarf, prior to the Cadmium II incident. Following the appearance of another Red Dwarf, The Dog encountered his counterpart, which he believed to be a "funny-looking dog." The two shared some time in the ship's disco. The Dog enjoyed himself, completely oblivious to The Cat's distaste for him.
The dog is dim-witted, excitable, and has terrible hygiene. The very mention of the word "bath" causes him pain. He has several dog-like tendancies: When he first meets The Cat, he offers to let him smell his "behind", and he is infested with fleas. He has what sounds like an American "hick" accent.
