Sarcoptes mites are [[Burrowing Mites|burrowing mites]] of dogs and foxes. They Cause [[Sarcoptic Mange]]. The mites prefer hairless skin and so begin on the hocks, elbows and pinnae. The mites are usually spread by direct host to host contact.

Sarcoptes mites are small, round mites. They have short legs that project only a short distance from the body margin. They have dorsal spines arranged in rows and a terminal anus. The male mites are about 250μm in length and the females are about 400-430μm in length.

Sarcoptes mites have a '''3 week''' life cycle. The female lays eggs in the epidermis in an '''egg laying pocket'''. The female feeds on liquid oozing from damaged tissue. The eggs then hatch in 1 week and '''6 legged''' larvae are released. They crawl to skin surface and then burrow back into the epidermis into '''moulting pockets'''.

The larvae moult to become '''8 legged''' nymphs. The nymphs moult twice before becoming adults. Adult males then emerge and look for females to mate.

Mite infection can be diagnosed with a skin scrape of a 'non-scratched' region. The presence of one Sarcoptes mite is diagnostic.
