Screw Tail: Strange Name for a Bad Condition
Kelly Serfas, a Certified Veterinary Technician in Bethlehem, PA, contributed to this article.
Screw tail is due to a malformation of one of several vertebrae in the tail. It most commonly occurs in Bulldogs, who have a clear genetic tendency for it. The condition can also rarely occur in pugs, Boston terriers and Manx cats. Other names for the condition include corkscrew tail, ingrown tail, tail fold dermatitis and tail fold intertrigo.
How bad is screw tail?
How severe the condition is depends on how deep the tail fold goes. In some cases, screw tail leads to an infected, painful and itchy skin fold.

Cleaning involves special shampoos, antiseptics, baths or medicated wipes.

The reason is that bacteria love the environment inside the skin fold because it is dark, warm and moist. Therefore, any liquid or ointment placed inside the skin fold maintains the moisture level. This is a classic, vicious cycle with no end in sight. Most of the clients I see for this problem are frustrated after months or often years of unsuccessful treatments and sometimes exorbitant veterinary bills. Unfortunately, if the case is severe, medical treatment will not be effective.
Surgery to fix screw tail
The best way to treat a bad case of screw tail is surgery. This entails removing the end of the tail and the infected skin fold in order to end up with a clean area. This is a fairly technical and challenging procedure, which is typically performed by a surgeon.
The challenges include:
- Working in a filthy area (both because
