Alternative Body Types
Dumbo rats have ears placed lower on the head, which are more open giving them a rounder appearance. The name is taken from the Disney elephant of that name.

There is no difference other than their ear placement which cannot be attributed to individual lines.

NFRS Standards, 2009: To be judged as standard rats with the following differences:
The ears to be set low on the sides of the head, their base at the back of the cheeks wider and more open than a standard rat. The ear is slightly furled at the top and will appear to be rose petal shaped, but gently pressing a finger to the back of the ear will show the ear as being perfectly rounded.
Head shape to follow the standard for normal eared rats, though may appear to differ due to the ear position. A prominent occiput (back of skull) is normal but should not present a ‘hunchback’ appearance.
Faults: creased, bent and wrinkled ears to be considered a serious fault. Also ears being too narrow and pointed and tubular rather than rounded to be considered a serious fault
Colour to conform to a recognised colour or pattern variety
Genetics: Due to a recessive gene with altered ear shape and position, tentatively named du
