Screw tail
Also known as: Corkscrew tail · Korkenzieherschwanz · Tail fold pyoderma · Ingrown tail · Schwanzfalten-Dermatitis · …
Overview
What it is
Tail curvature (Rutenkrümmung), commonly known as screw tail, is a congenital malformation of the tail bones, or caudal vertebrae, which causes them to develop in a twisted or spiral shape. This skeletal abnormality primarily affects short-nosed dog breeds and results in deep, poorly ventilated skin folds at the base of the tail. These tight folds easily trap moisture and debris, leading to localized skin inflammation.
How it presents
Owners will typically notice symptoms starting in puppyhood, including a foul odor, redness, itching, and pain around the tail base. Dogs often lick the area more or scoot their rear along the ground. In severe cases, the curved tail can grow painfully into the surrounding skin.
Treatment
Mild cases require lifelong daily cleaning and topical care of the tail folds, while severe or chronic infections are treated with a one-time surgical removal of the tail. The typical cost for managing this condition, including surgery if needed, ranges from 400 to 2500 EUR.
