Demodectic<unk>  A dog with severe demodectic<unk>  Also called demodicosis or red<unk> , demodectic<unk>  is caused by a sensitivity to and overpopulation of Demodex spp. The two types of demodectic<unk>  are localized and generalized. Localized consists of four spots or less. Demodex is not zoonotic and is not transferable across species. Each host species has its own species of Demodex. For example, dogs are hosts to Demodex canis and cats are hosts to Demodex cati. A type of demodectic infection in humans is known, but is less commonly symptomatic. See Demodex folliculorum. Sarcoptic<unk>  A street dog in Bali, Indonesia, suffers from demodectic<unk>  Sarcoptes scabiei Puppy with sarcoptic<unk>  Sarcoptic<unk> , also known as canine scabies, is a highly contagious infestation of Sarcoptes scabiei var. canis, a burrowing mite. The canine sarcoptic mite can also infest cats, pigs, horses, sheep, and various other species. The human analog of burrowing mite infection, due to a closely related species, is called scabies (the "seven-year itch"). Burrowing mites are in the family Sarcoptidae. They dig into and through the skin, causing intense itching from an allergic reaction to the mite's feces, 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<unk>  are often in poor condition, and in both animals and humans, immune suppression from starvation or any other disease causes this type of<unk>  to develop into a highly crusted form in which the burden of mites is far higher than in healthy specimens.
