What is sarcoptic mange?

Sarcoptic mange in dogs (also known as scabies in dogs) is a highly contagious skin condition caused by microscopic Sarcoptes mites. Sarcoptic mange is an extremely itchy skin disease. The dog variety of the mite can also infest humans and cause temporary dermatitis with intensely itchy skin lesions that can last for several weeks.

What is demodectic mange?

Demodectic mange is caused by microscopic Demodex mites that live in the dog’s hair follicles. Demodex mites are a normal inhabitant of a dog’s skin, however, they can cause skin disease if the immune system cannot control the mite population (e.g. young or malnourished dogs).

What is otodectic mange?

Otodectic mange is a common condition, especially in puppies, caused by ear mites (Otodectes cynotis). Ear mites can cause intense ear irritation and discomfort. These tiny parasites feed on wax and oils in a dog’s ear canals. They can result in head shaking or scratching, rubbing of the ears and secondary ear infections.

You should consult with your vet if you notice any signs of skin disease such as scratching, hair loss or scabs on the skin.
