Mange is a highly contagious skin condition caused by microscopic mites that burrow into a dog's skin or hair follicles. While treatable, it causes significant discomfort and requires prompt veterinary attention. Understanding the different types, symptoms, and treatment approaches helps ensure your dog receives appropriate care.
Types of Mange
Sarcoptic mange (scabies) is caused by Sarcoptes scabiei mites and is highly contagious to other dogs and humans. It causes intense itching, hair loss, and crusting, typically affecting ears, elbows, hocks, and abdomen. Demodectic mange results from Demodex mites, which normally live harmlessly in small numbers on healthy dogs. It becomes problematic when the immune system is compromised, causing localized patches or generalized hair loss without severe itching.
Recognizing Symptoms
Watch for intense scratching, biting, or rubbing affected areas. Hair loss appears as bald patches that may spread. Skin becomes red, inflamed, and may develop crusty lesions or sores from self trauma. Secondary bacterial infections can cause oozing, odor, and fever. Sarcoptic mange shows more severe itching, while demodectic mange often presents as non itchy bald spots initially.
Diagnosis Process
Veterinarians diagnose mange through skin scrapings examined under a microscope to identify mites, eggs, or fecal material. Multiple scrapings from different areas may be needed, especially for sarcoptic mange where mites are harder to find. In some cases, response to treatment confirms the diagnosis even if mites aren't visible.
Treatment Approaches
Sarcoptic mange requires antiparasitic medications (oral, topical, or injectable), medicated baths, and thorough environmental decontamination since mites can survive off the host. All dogs in the household need treatment. Demodectic mange in young dogs often resolves as their immune system matures. Generalized cases require antiparasitic treatments and management of underlying immune issues. Secondary infections need appropriate antibiotics.
Home Care and Prevention
Complete the full treatment course even if symptoms improve quickly. Wash all bedding, collars, and grooming tools in hot water. Vacuum living areas thoroughly. Avoid contact with stray or unknown dogs. Maintain your dog's overall health through proper nutrition, regular veterinary care, and parasite prevention to support immune function.
