The supracaudal gland (violet gland), which is found on a dog's tail, secretes oils, lipids, and protein. Sometimes, this gland secretes too much androgen, which can raise levels and can cause a bare spot in that area called stud tail (supracaudal gland hyperplasia). … Stud tail can be very irritating to your dog.
Also called tail gland hyperplasia, stud tail refers to overactive glands on the top of the tail. These glands produce waxy excretions that result in hair loss and crusty lesions. In severe cases, the condition can make the tail vulnerable to bacterial infections.
Shampoos, particularly antiseborrheic shampoos, are used regularly to keep the area clean. Antibiotics may be necessary to treat infection, if present. Neutering may resolve symptoms of stud tail for intact male cats.
In dogs, the violet or supracaudal gland is found approximately above the 9th caudal vertebra, but depending on breed it may be vestigial or entirely absent. The violet gland secretes protein and hydrophobic lipids, has wide excretory ducts, is connected with coarse hairs, devoid of cysts, and has no sexual dimorphism.
Treatment. Treatment of cases of feline acne and stud tail involves removal of excess sebum and hence prevention of comedone formation and secondary infection. An antibacterial wash, such as chlorhexidine, can be used for this purpose, initially two or three times daily.
Some of the types of shampoo include antiseborrheic shampoos with chlorhexidine or benzoyl peroxide. This should be used on the affected area at least two times a day. In severe cases of recurrent infection, surgery to remove the gland will be done. However, this is not common and only done in severe cases.
Generally speaking, skin infections are not clinical emergencies. If you have noticed that the skin on your dogs tail-tip is turning black, contact a veterinarian and arrange for an appointment.
