Dumbo: Ears are larger, and lower on the head. Named after the elephant, Dumbo.
Standard: Rats should be of good size, does long and lean, bucks having a bigger build, arched over the loin, with clean, long head without too pointy a nose. The eyes should be round, bold, and clean. The ears should be good sized, well formed and widely spaced. The tail should be as long as the body, thick at the base and tapering to a fine point. The ears, feet, and tail should be covered in a fine hair.
Tailless: Shortened body length which is more rounded. The hind legs should be slightly longer than the front. The “rumpy” is completely tailless.
