Screw TailScrew 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. The tail can partially obstruct the anus, in which case feces and anal sac fluid enhance the skin infection. The tail fold may then become painful and itchy. In most cases, the smell is so terrible, that it is sometimes difficult to breathe near the poor dog!

Skin fold dermatitis, a skin infection between the folds of skin, can be treated with antibiotics by mouth or inside the skin folds along with daily cleaning of the skin folds. Cleaning involves special shampoos, antiseptics, baths or medicated wipes.

Ironically, while cleaning the skin fold helps treat the infection, it can also make it worse. 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.

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:
