Question

why dogs tail is curve

Answer 1

--------------------------------------------------------
Pugs and some Bulldogs have corkscrew shaped tails. This tail shape can be caused by vertebrae that have either fused or are wedge-shaped. The medical term for this condition is hemivertebrae. It's common in these breeds and not a concern as long as it effects the only the tail.
