Brachyuria (stumpy tail)
Brachyuria (stumpy tail)
General description
This genetic analysis allows the distinction between a short tail of a natural origin or a docked tail, which is forbidden in most countries. Homozygous genotypes are lethal.

Detailed description
The appearance of dogs differs in coat colour, hair length as well as in the tail length. Particularly the tail length bestows the characteristic look of most dog breeds. To dock the tail is forbidden in most countries. A genetic analysis allows the confirmation of a natural origin of a short tail. By mating two heterozygous dogs the quantity of the litter is reduced because of the homozygous genotype being lethal. This is another reason for performing the genetic test.
In six additional breeds studied there is no correlation between the analysed mutation and a short tail: Boston Terrier, English Bulldog, King Charles Spaniel, Miniature Schnauzer, Parson Russell Terrier, Rottweiler
