What is Folliculitis in Dogs, and how to detect it?

Folliculitis is a skin infection that is quite frequent in dogs. When a hair follicle is irritated, the region inflates, resulting in swelling, redness, itching, discomfort, and other skin problems. Although no dog breeds are genetically susceptible to folliculitis, dogs with allergies are more likely to get the disease. There are several reasons, all of which need veterinarian care. If you suspect your dog has folliculitis, bring them to animal medical center Virginia Beach VA.

What Is Folliculitis and How Does It Affect You?

Folliculitis is the medical term for the irritation of a hair follicle caused by a bacterial infection. Hair grows through microscopic pores in the skin called hair follicles. Folliculitis occurs when one or more follicles become inflamed or infected, producing inflammation in the surrounding region. 

Folliculitis Symptoms in Dogs Symptoms

  • Discoloration
  • Swelling 
  • Oozing pus
  • Psoriasis
  • Collarettes for epidermis
  • Hyperpigmentation

Folliculitis causes one or more skin blemishes on the body in dogs. It may begin as a tiny elevated region of skin that seems to be acne (called an abscess). It’s possible that the area will get more elevated and filled with pus (called a pustule). Folliculitis can result in itching, discomfort, and patchy hair loss (alopecia) on one or more parts of the dog’s body. Epidermal collarettes are crusty or flaky circular skin lesions that occur in some dogs. Hyperpigmentation (dark patches on the skin) may also develop in the afflicted areas.

Folliculitis Causes

Folliculitis occurs when one or more hair follicles are irritated by one of the following illnesses:

  • Infection with bacteria (often Staphylococcus bacteria)
  • Infections caused by viruses or fungi
  • fleas, ticks, or mites
  • Trauma
  • Systemic ailments

Diagnosing Folliculitis in Dogs

Consult your veterinarian if you suspect your dog has folliculitis or any other skin issue. Your veterinarian at pet care Virginia Beach will do a checkup and may be able to identify folliculitis by visual examination after reviewing details about your dog’s symptoms and history. However, to pinpoint the particular reason, more testing is frequently required. The following are examples of possible testing:

  • Under a lens, skin cytology examines cells.
  • Scrape your skin to look for parasites like mites.
  • Skin biopsy is a surgical procedure in which small skin samples are taken and submitted to a medical examiner for study.
  • Cultures of fungi or bacteria
  • Organ efficiency and blood cell levels are assessed using blood tests and urinalysis.


The etiology of folliculitis in dogs determines the therapy. Systemic drugs and topical treatments such as sprays, lotions, ointments, and shampoos are commonly used in treatment.

The most common treatment for pain and inflammation is topical therapy. Your veterinarian may advise you to take regular baths using a medicated cleanser. In sprays, moisturizers, lotions, steroids, bactericidal, and antifungal medicines are commonly prescribed.

Oral antibiotics are frequently used to treat bacterial folliculitis. To remove the germs, a long course of therapy may be required. Antifungal drugs are required for fungal folliculitis. Certain fungal infections also need long-term therapy.

Parasitic infections require both parasite-killing drugs and supportive care to facilitate recovery. A subsequent infection may still require antibiotic treatment.

If a systemic condition is causing folliculitis, it must be addressed in conjunction with the skin infection. Long-term or lifetime therapy may be required, depending on the condition.
