Introduction
“Mange” is one of those conditions that cause even the most devoted owner to become reluctant to pet their dog. Much confusion surrounds “mange” in dogs, including the possible treatments for the disease and whether or not it can be passed from dogs to people. “Mange” is a general term for several types of parasitic mite infection. Only certain types of mange are contagious between dogs, or from dogs to people.
Types of Mange in Dogs
Sarcoptic Mange
The type of “mange” that most dog owners think of - the highly-contagious mite infestation that causes intense itching and rapidly infects other animals, including people - is caused by Sarcoptes scabei mites. These mites burrow deeply into the skin, causing profound itching and giving the skin a “crusty” appearance. Sarcoptic mange should be treated with topical medications that your veterinarian can prescribe. All animals in the household should be treated, regardless of the presence or absence of clinical signs, given the highly contagious nature of this infection.
Demodectic Mange
Demodectic mange, also known as “red mange,” is caused by the Demodex mite which lives and breeds in the hair follicles of dogs. Demodex mites are normal residents (in small numbers) of the hair follicles and sebaceous glands of healthy dogs. However, in puppies and in older dogs with compromised immune systems, these mites can proliferate and cause hair loss, skin thickening and other clinical signs. Demodectic mange is not contagious to people or other animals and normally does not cause pruritus (itchiness). Demodectic mange can be treated through immune support, oral medication and prescription dips.
Ear Mites
Ear mite infestation is generally not referred to as “mange,” but the clinical signs are very similar. Canine ear mites are highly contagious between dogs. However, they do not infect people. These mites need to be treated with prescription topical medications.
Cheyletiellosis
Cheyletiellosis is a highly contagious, zoonotic skin mite infestation of dogs and cats. It is commonly called “walking dandruff.” This type of mange can be treated with prescription shampoos and topical skin treatments. People can become infected by this mite.
