So what’s actually behind canine with out tails, and the way did this uncommon trait seem in sure breeds?
Nature’s Shortcut: Why Some Canine Are Born Bobtailed
Stumpy-tailed canine are pups born with naturally brief tails, generally known as bobtails.
In naturally bobtailed canine, the vertebrae within the tail don’t totally type throughout fetal growth within the womb. This doesn’t hurt the canine; it simply leads to totally different tail lengths inside the identical breed and even the identical litter.
Tail size can fluctuate broadly, from full-length tails to brief stubs to almost none in any respect. That’s why two puppies born aspect by aspect can look fully totally different from behind — a reminder that genetics, not scissors, determine the wag.

Right here’s the brief model:
- The mutation acts in an autosomal dominant manner — one copy is sufficient to shorten the tail.

What About Canine With Screw Tails?
Not all brief tails are created equal. Some canine have what’s generally known as a “screw tail.” A screw tail seems tightly curled, corkscrew-shaped, or kinked.
However this isn’t the identical because the pure bobtail attributable to the T-box gene mutation. As an alternative, it’s the results of vertebral malformations, the place the small bones (vertebrae) within the tail are fused or misshapen throughout growth.

That’s why specialists emphasize that screw tails aren’t the identical as bobtails. Nonetheless, for a lot of canine, that little corkscrew is a part of their unmistakable appeal.
