Folliculitis is a skin condition that can affect dogs and is caused by an infection or inflammation of the hair follicles. It can cause redness and inflammation around the hair follicles. There might be pimples or pustules on the skin, especially in areas with hair, such as the neck, back, and legs. Your dog may show signs of itching and discomfort. Additionally, you may notice crusting, scabbing, and hair loss over the affected areas. Folliculitis can be caused by a variety of factors, including bacterial, fungal, or yeast infections, allergies, and parasites. Treatment will depend on the underlying cause of the folliculitis and may involve antibiotics, antifungal medications, or other therapies to manage the symptoms. If you suspect that your dog has folliculitis, it's important to consult with your veterinarian for a proper diagnosis and treatment plan.
