Here are some pictures of two Black-Backed Jackals taken in Namibia affected by mange... A more severe case of mange... What is Mange? Mange is a class of persistent contagious skin diseases caused by parasitic mites. The term is sometimes reserved for the infestation of domestic animals. Another term used to describe mite infestation is acariasis. These mites embed themselves either in hair follicles or skin, depending upon their type. They generally infest domestic animals, including dogs and other canines, livestock (such as sheep scab), wild animals and even humans (such as scabies). Two types of mites produce canine mange, and each type has characteristic symptoms. Demodectic Mange Also called demodicosis or Red Mange, demodectic mange in dogs is caused by a sensitivity to and overpopulation of Demodex canis as the animal's immune system is unable to keep the mites under control. There are two types of demodectic mange: localized and generalized. Localized consists of 4 spots or less. Most dogs are immune to demodectic mange, however dogs with compromised immune systems and the elderly are at a higher risk. It is not contagious to humans. Sarcoptic Mange Also known as canine scabies, sarcoptic mange is a highly contagious infestation of Sarcoptes scabiei canis, a burrowing mite. The canine sarcoptic mite can also infest humans (scabies), cats, pigs, horses, sheep and various other species. These mites dig into and through the skin, causing intense itching and crusting that can quickly become infected. Hair loss and crusting frequently appear first on elbows and ears. Skin damage can occur from the dog's intense scratching and biting. Secondary skin infection is also common. Dogs with chronic sarcoptic mange are often in poor condition.
