The dog scent gland on tail is a fascinating topic. Located on either side of the anus, these glands produce a strong-smelling secretion that dogs use to mark their territory.
This secretion is made up of pheromones, which are chemical signals that convey information between dogs. A dog's scent gland on tail is a vital part of their communication and social behavior.
To keep your dog's scent gland on tail healthy, make sure to clean the area regularly, especially after walks or playtime. This will help prevent irritation and infections.
Regular grooming can also help reduce the risk of skin problems and keep the area clean.

What Is That Dark Patch on My Dog?
The dark patch on your dog's tail is actually a gland located on the tail, not an anal gland. This gland is called a "violet" or "supracaudal" gland.
It secretes certain substances and the area is rich with apocrine and sebaceous glands, which causes the color change. The exact function of this gland in dogs remains unknown, but some believe it may help identify them to other canines.
In dogs, the tail gland is not as developed as it is in foxes, which use it for communication purposes and to scent mark their territory.

Understanding the Scent Gland
The scent gland, also known as the tail gland, is located just above the dog's 9th caudal vertebrae. Depending on the breed, it may be vestigial or entirely absent.
This gland is connected to coarse, stiff hairs and can be found in both male and female dogs. Some breeds are more prone to having a visible tail gland than others.
The skin over the tail gland is prone to developing an accumulation of excess oil, which can clog hair follicles and cause localized hair loss and comedones.
Location of the Gland
The location of the scent gland in dogs is a fascinating topic. The tail gland is an oval area located just above the dog’s 9th caudal vertebrae. Depending on the breed, it may be vestigial or entirely absent.
In some cases, the tail gland is connected with coarse, stiff hairs.
Skin Characteristics
The skin over the tail gland is prone to developing an accumulation of excess oil, which can clog hair follicles and cause localized hair loss and comedones. This can lead to infection of the skin in and around the hair follicles, known as folliculitis and furunculosis.

In unneutered male dogs, the presence of testosterone can cause the supracaudal tail gland to swell, leading to hair loss or even some bulging in this area. Neutering can resolve these issues.
The skin in this area can also be affected by hormone imbalances, such as low thyroid hormone, an imbalance of sex hormones, or elevated steroid hormones (Cushing's disease). These imbalances can cause the hair cycle to arrest, leading to hair loss.
Here are some factors that can predispose a pet to developing stud tail:
- Allergic skin disease
- Secondary bacterial or yeast skin infection
- Demodex infection
- Sex hormone imbalance
- Hypothyroidism
- Cushing’s disease
Hypothyroidism can cause changes to the skin, such as scaling and a tendency to have skin infections. It's a common endocrine condition found in dogs, especially in middle-aged dogs.
Potential Problems
While many dogs won't experience any issues with their scent gland, it can become infected.
Inflammation or infection of the supracaudal gland can cause problems, such as a swollen gland and hair loss, leading to a bald, greasy spot at the top of the tail.
Dogs may require a course of antibiotics in severe cases.
Tumors can also develop in this area, so it's essential to see a vet if you suspect any issues.
Dog Health Risk
Middle-aged dogs are often affected by stud tail, although it can occur in any dog and of any breed.
Intact male dogs are more commonly affected, but female dogs can also develop stud tail.
Damage typically appears at the base of the tail, causing hair loss, crusting, scaling, blackheads, greasy deposits, and excessive skin flaking.
Darkening of the skin due to persistent inflammation is also possible.
A bald spot on the tail can occur due to hair loss, a common symptom of stud tail.
Small raised bumps, pus-filled blisters, or oozing sores may be present if there's a secondary bacterial infection.
The affected dog may scratch the base of its tail, further exacerbating hair loss.
Treatment and Care
Regular bathing is a crucial part of managing tail gland hyperplasia in dogs.
Using a veterinary shampoo can help cleanse the area and reduce oiliness and crusting. This can make a big difference in your dog's comfort and overall health.
A balanced diet can also be very beneficial. Feeding a diet high in omega fatty acids (DHA/EPA) or supplementing with fish oil can promote healthy skin and coat.
Best Shampoo for Treatment
When treating stud tail in dogs, using the right shampoo can make a big difference. Two effective options are Dechra's shampoo and PetMd's shampoo, both of which contain Benzoyl peroxide.
Dechra's shampoo contains 2.5% Benzoyl peroxide, while PetMd's shampoo contains 3% Benzoyl peroxide. These shampoos also contain salicylic acid, with Dechra's containing 1% and PetMd's containing 2%.
Regular bathing with a veterinary shampoo can help manage tail gland hyperplasia in dogs. Using a shampoo with Benzoyl peroxide and salicylic acid, such as Dechra's or PetMd's, can be particularly helpful.
Here are some key ingredients to look for in a shampoo for stud tail:
By using the right shampoo and following a regular bathing schedule, you can help keep your dog's tail gland area clean and healthy.
Coconut Oil for Stud Treatment
Coconut oil can be a helpful addition to stud tail treatment, but it's not a replacement for proper treatment.
While using coconut oil alone won't be enough to treat a skin infection, it can help increase the skin's hydration when used after a medicated shampoo.
Coconut oil can be used after shampooing with a medicated shampoo containing benzoyl peroxide and salicylic acid, which can improve skin texture and reduce skin inflammation.
It's also worth noting that coconut oil is part of some cleaning and moisturizing shampoos, such as DermaLyte shampoo, which can be useful for dry forms of seborrhea.
