Here’s a primer on the two most common types of mange in dogs — sarcoptic and demodectic — in compare and contrast style.Sarcoptic Mange — infection of the skin with the microscopic, parasitic mite Sarcoptes scabei. is contagious, and most dogs catch the disease via direct contact with an infected individual. People and cats can also be transiently infected.Demodectic Mange — overgrowth of mites, Demodex sp., that are normally found in small numbers in a dog’s skin. is usually diagnosed in young dogs without fully functioning immune systems, or in dogs that are otherwise immunocompromised. Demodectic mange is not contagious.Sarcoptic Mange — extreme itchiness with hair loss and red scaly skin that typically start in sparsely-haired areas like the ear flaps, elbows, and abdomen, but can spread to the entire body without effective treatment.Demodectic Mange — patchy hair loss with relatively normal looking skin underneath is the hallmark of the most common, localized form of the demodectic mange. Mild to moderate itching may or may not be present. In more severe, generalized cases, hair loss may be wide-spread, the skin obviously abnormal, and itchiness severe.Sarcoptic Mange — if skin scrapings reveal the mite, a diagnosis of sarcoptic mange is easily reached. However, dogs may react so intensely to a small number of mites that skin scrapings can be falsely negative. A tentative diagnosis is often reached based on a dog’s clinical signs and response to treatment.Demodectic Mange — multiple skin scrapings usually will reveal the presence of higher than normal numbers of mites.Sarcoptic Mange — dips, injections, oral drugs, and spot-on treatments can all be used to treat sarcoptic mange. Determining which option is best depends on a dog’s breed, health, and other considerations, but my favorite treatment is selamectin because of its safety, efficacy, and ease of use. Every dog in the home should be treated to prevent animals from reinfesting each other.Demodectic Mange — mild cases of localized demodectic mange often resolve without any treatment when a dog’s immune system becomes better able to control mite numbers. Antibiotics, drugs that kill the mites, and medicated dips and ointments can all be prescribed in more severe cases. If an underlying cause of immunosuppression can be identified, it should also be dealt with.Dr. Jennifer CoatesImage: / via
Affected dogs need to be isolated from other dogs and their bedding, and places they have occupied must be thoroughly cleaned. Other dogs in contact with a diagnosed case should be evaluated and treated. A number of parasitical treatments are useful in treating canine scabies. (a mixture of calcium polysulfides) rinses applied weekly or biweekly are effective (the concentrated form for use on plants as a fungicide must be diluted 1:16 or 1:32 for use on animal skin).

There are several ways to treat scabies. In the past, the most effective treatment had been to clip the dog if he had long hair, bathe him with a benzoyl peroxide shampoo to cleanse the skin, and then apply an organophosphate dip (Paramite). Amitraz dips and Mitaban (also organophosphates), and lime sulfur dips (Lymdip) have also been used effectively. The dogs are usually dipped once every two weeks for two to three times. While effective, these dips are very unpleasant to apply for both the owner and the dog. Because the dip must come in contact with the mites and many mites live on the face and ears of dogs, great care must be exercised when applying these dips to these sensitive areas. The dips can be toxic to humans and are not suitable for very young, old, or debilitated animals. In addition, there are some reported cases of resistance to these dips in some cases of sarcoptic mange.

Trying to make a diagnosis of canine scabies can be very frustrating. The standard method is to perform a skin scraping and then identify the mite under the microscope. Unfortunately, on average, only twenty percent of the infected dogs will show Sarcoptes mites on any given scraping. Therefore, if a dog has a positive skin scraping, the diagnosis is confirmed but a negative scraping does not rule out sarcoptic mange. Therefore, most diagnoses are made based on history and response to treatment for scabies.
