Folliculitis is the inflammation of the hair follicles and can occur due to allergies, bacterial infections, or other conditions. In some cases, the hair follicles can become infected, forming whitish or yellowish-white pimples.
This condition can be identified by the wounds that appear on the surface of the skin, swellings, or crusts of dead skin. To treat folliculitis, the veterinarian can prescribe a special type of shampoo, medicated spray, oral antibiotic, or antibacterial ointment to relieve itching and successfully treat the condition.
In this article, you will learn what folliculitis in dogs is, its clinical signs and causes, how it is diagnosed, and the treatment for this dermatological condition.
What Is Folliculitis in Dogs?
Folliculitis is a dermatological condition, meaning it is a skin disease. It is characterized by the inflammation of the hair follicles and is manifested by the occurrence of red spots and small swellings on the skin.
In some cases, these small bumps can become infected and form pustules (pimples) that have whitish-yellow ends. When the condition reaches this point, it is commonly discussed in veterinary medicine as bacterial folliculitis. In dogs, folliculitis is the most common kind of skin infection. This condition is often confused with acne.
Folliculitis occurs when the dog suffers from another, unidentified underlying illness, such as allergies, Cushing disease, or disorders of the immune system, or was subjected to skin trauma. In other words, if the primary condition is diagnosed and treated in time, folliculitis will not occur.
Dogs suffering from folliculitis will show several clinical signs, including excessive scratching, hyperpigmentation, and hair loss. Folliculitis is not a condition that can put your dog’s life in danger, but it cannot be treated at home, and a visit to the veterinarian is necessary.
What Are the Signs of Folliculitis in Dogs?
Folliculitis in dogs has specific clinical signs by which you can tell if your pet suffers from this skin condition. First, you will notice small red bumps (papules) on your dog’s skin, which are similar to acne. Over time, these papules can become infected and turn into pustules (vesicles filled with pus).
Due to folliculitis, your dog can experience intense itching, excessive scratching, pain in the affected area, and hair loss. Your pet’s skin color may also change, becoming darker. In some cases, the affected dogs may develop raw skin lesions called epidermal collarettes (circular scabs with darker skin, which are basically “footprints” of a pustular lesion).

In most cases, folliculitis in dogs is a skin problem caused by a bacterial infection of the hair follicles. It is usually caused by a bacteria called Staphylococcus, but it can also be caused by other types of bacteria.

How Is Folliculitis Treated in Dogs?

The main condition that led to the development of folliculitis will be treated first.

Systemic medications, such as antibiotics, thyroid medication, etc. are prescribed if your dog’s folliculitis is caused by a systemic disease.
