1. Sarcoptic Mange (Scabies):
* Cause: Caused by the Sarcoptes scabiei mite, which burrows into the skin and lays eggs.
* Transmission: Direct contact with infected dogs or indirect contact with contaminated objects like bedding or grooming tools.
* Symptoms: Intense itching, hair loss, crusting, and scabs, especially on the ears, legs, belly, and head.
2. Demodectic Mange (Demodicosis):
* Cause: Caused by the Demodex canis mite, which lives in the hair follicles of dogs.
* Transmission: Often inherited from parents or passed on through close contact with an infected dog.
* Symptoms: Redness, scaling, hair loss, and crusting. Can be localized (small patches) or generalized (extensive hair loss).
Here's a summary:
* Sarcoptic Mange: Highly contagious, can be passed from dog to dog and even to humans.
* Demodectic Mange: Less contagious, typically affects dogs with weakened immune systems.
Other factors that can increase the risk of mange in dogs:
* Compromised immune system: Due to illness, stress, or medication.
* Poor hygiene: Unsanitary living conditions or infrequent bathing.
* Age: Puppies and senior dogs are more susceptible.
* Breed: Certain breeds, like American Bulldogs and Doberman Pinschers, are predisposed to Demodectic mange.
If you suspect your dog has mange, it's important to take them to a veterinarian for a diagnosis and treatment plan.
