Brachyury(NBT)
Also known as: Natural Bobtail · Congenital short tail · Angeborene Kurzschwänzigkeit · Stummelrute · Anury · …
Overview
What it is
Brachyury is a congenital condition affecting the skeletal system where a dog is born with an unusually short or completely absent tail. It is caused by an autosomal-dominant genetic mutation in the T-box gene, which plays a key role in embryonic skeletal development. This mutation alters how the tail vertebrae form before birth, resulting in a naturally bobbed tail.
How it presents
Owners will notice a shortened or missing tail immediately at birth. Because this is a structural variation rather than a progressive illness, it does not cause pain or affect the dog's mobility or quality of life.
Treatment
No treatment is required or recommended as this is a harmless anatomical variation. Consequently, there are no medical costs associated with this condition, placing the expected lifetime treatment cost at 0 EUR.
