Key points about mange:

Types of Mange:

  • There are two main types of mange:
    • Sarcoptic mange (caused by Sarcoptes scabiei mites) and Demodectic mange (caused by Demodex mites).
    • Sarcoptic mange is highly contagious and can affect both animals and humans, while Demodectic mange is less contagious and is usually species-specific.


  • Symptoms of mange include intense itching, hair loss, redness, and inflammation of the skin. In severe cases, crusts and scabs may form, and secondary bacterial infections can occur due to the damaged skin.


  • Mites causing mange can be transmitted through direct contact with an infected animal or through contaminated bedding, grooming tools, or living areas. Sarcoptic mange mites can survive off the host for a short period, increasing the risk of transmission.


  • Veterinarians typically diagnose mange through skin scrapings, where they collect samples of skin cells and examine them under a microscope to identify the presence of mites or their eggs.


  • Treatment for mange usually involves medications such as topical ointments, oral medications, or injections, depending on the severity of the infestation and the type of mite involved. Antibiotics may also be prescribed to treat secondary bacterial infections.

Environmental Management:

  • Along with treating the affected animal, it's essential to clean and disinfect the living environment to prevent re-infestation. Washing bedding, vacuuming living areas, and treating other pets in the household may be necessary.


  • The prognosis for mange varies depending on factors such as the type of mite, the overall health of the animal, and how early the condition is diagnosed and treated. With proper treatment and management, many animals recover from mange successfully.


  • Preventing mange involves keeping pets clean and healthy, avoiding contact with infected animals, and regularly cleaning living areas. It's also crucial to promptly treat any signs of mange to prevent the spread of the disease to other animals or humans.
