Body type


Dumbo rats originated in the North West of America in the 1990s, and finally made their way over to the UK in May 1999. The initial imports of Siamese dumbos were quickly followed by a rainbow of different dumbos being imported, and we now have dumbos in pretty much every possible colour and marking.

It may seem odd now, considering how ubiquitous they are, but originally in the UK dumbos were quite a controversial variety. The rumours of dumbos being more laid back than “normal” rats led to fears that there could be something more to the variety than simply a different earset, and they were banned from NFRS shows until it was shown that they were perfectly ordinary and standard rats.

Genetics: A simple recessive gene, not scientifically described but in the fancy usually given the symbol dudu

NFRS standard: 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. Dome skulls, fore shortened head, misplaced or small eyes to be judged as a serious fault. Colour to conform to a recognised colour or pattern variety.
