Scabies (Sarcoptes)

Scabies is a contagious, very itchy skin condition that can occur at any time of the year. It is caused by a mange mite named Sarcoptes scabei. The mites prefer less hairy parts of the body such as ears, elbows, belly and hocks (ankles.) Affected areas may have hair loss, yellow crusts, redness, and have a secondary bacterial infection.

Scabies can be a difficult skin condition to diagnose. It may require multiple skin scrapings to find the mites as they burrow deep into the skin. Often treatment for mange is started based on the skin lesions and signs alone. The mites generally live about a month and reproduce about every three weeks, so multiple exams may be necessary.

Treatment for scabies usually involves special shampoos, oral or injectable medication and sometimes dipping. Dogs with long, thick fur may need to be clipped to be effectively treated for mites. Dogs that are extremely itchy often have secondary bacterial infections and require a short course of antibiotics and/or anti-inflammatory medication. Treatment is usually continued for one month after symptoms resolve.

The sarcoptes mite which causes scabies in animals can be transmitted to humans, so care should be used when handling an infected animal. The infection in people is transient, but can be very irritating. Please consult you personal healthcare professional if you have any questions regarding infections in people.
