Canine scabies is caused by a mite called Sarcoptes scabiei var. Canis. Although extremely small, these mites can cause severe itching and skin irritation that will decrease a dog's quality of life significantly. The female mites dig into the superficial layers of the skin to lay their eggs. Once the eggs hatch, the larvae migrate nearby and then dig deeper into the skin to mature into adults. This process causes severe inflammation, irritation, itching, and rashes. With a 21-day life cycle, the mites can replicate quickly, causing a rapid increase in numbers and more skin irritation over larger areas.
The mites can be passed to other animals, such as cats, foxes, and humans. People who have acquired mites will develop itchy red bumps on their body. These lesions last for approximately two weeks, after which they usually disappear on their own. Repeated contact with the affected animal can cause the lesions to remain for long periods of time. A medical dermatologist should be consulted about any human skin lesions or questions about mites.
