Violet gland

A Rhodesian Ridgeback (sex unknown) with "stud tail": the violet gland lost hair and appears as a dark dimple

The violet gland or supracaudal gland is a gland located on the upper surface of the tail of certain mammals, including European badgers and canids such as foxes, wolves,[1] and the domestic dog,[2][3][verification needed] as well as the domestic cat.[4] Like many other mammalian secretion glands, the violet gland consists of modified sweat glands and sebaceous glands.

It is used for intra-species signalling, scent marking, and contributes to the strong odor of foxes in particular. Although it secretes a mixture of volatile terpenes similar to those produced by violets (hence the name), the chemicals are produced in much greater quantity than in flowers, and the resulting strong smell can be quite unpleasant.
