Tail Gland of Dogs and Cats
Both dogs and cats have an oil scent gland on the top of the tail near the base. The supracaudal gland is described in Miller’s Anatomy of the Dog as having fewer hairs per follicle associated with sebaceous glands that produces oily discharge. The area of the tail may have benign enlargement and become hairless with age. The oil glands can serve in grooming to repel water from the fur.
The gland is prone to the follicles being plugged causing blackheads or comedones. The follicles can be cleaned of superficial dead skin and the comedones squeezed to relieve the plug.
Stud tail is a common term used to describe over active tail glands with hair loss and excess oil production.
In advanced cases of stud tail, glands have excess discharge and odor due to an infection of the follicles requiring medical attention. Rarely the gland develops tumors requiring removal of the area or tail.
