Bacterial Dermatitis (canine folliculitis)
Pyoderma is a common disease in dogs and is caused by bacteria infecting the skin. Most bacterial skin diseases are usually treated with daily oral antibiotics and medicated baths 2-3 times weekly. There are three main types of pyoderma, depending on severity: surface, superficial, and deep.
Surface pyodermas are often called "Hot Spots". This condition causes a painful, inflamed area of skin and usually has a discharge and bad odor. Contributing causes are allergies, parasites, and poor grooming. Lesions often spread rapidly to the surrounding skin. Successful treatment involves controlling the itch with corticosteroids, and sprays and clipping the hair away to prevent spreading.
Superficial pyodermas are deeper infections and frequently have pustules and folliculitis present. They can be recurrent chronic problems. Staph bacteria may be very pruritic and can actually be a cause of allergies in some dogs. Treatment includes antibiotics, and benzoyl peroxide shampoos.
Deep Pyodermas may be localized or generalized, but usually involve the face, feet, and pressure points. The infections frequently drain pus and need long term (4-8 weeks) antibiotic therapy to control ,in addition to the medicated baths. Sometimes immune stimulants, such as immunoreglan or staph lysate, can be given by your veterinarian to help heal these serious infections.
