What Are the Treatments for Demodex Mange?

Demodex mange is caused by a small parasite that burrows under your pet's skin. The parasite in question is a mite, and the result of an infestation is that the dog will lose patches of fur and develop lesions on its body. Usually puppies and dogs with weakened immune systems are most susceptible to demodex mange, but any dog can be impacted. Knowing the treatment options can help your discussion with your veterinarian.

  1. Insecticides

    • Although some milder forms of mange can resolve spontaneously with time, you may still want to treat your pet to speed the healing process. Your vet will likely prescribe an insecticide that is safe for topical use on your dog. These insecticides often contain rotenone. According to the Resource Guide for Organic Insect and Disease Management from Cornell University, rotenone is a botanical insecticide that slowly poisons and kills the mite. If the effects of the mites are minor, hair usually regrows within about a month after treatment.

    Dips

    • Dips are a common treatment for more intense cases of mange. These products contain amitraz and generally are used when the mite infestation is not localized to a single area. Often, before application of the dip, the area surrounding the infestation is shaved. According to PetEducation.com, generally the dip is applied three to six separate times over a six to 12-week period. However, most vets will not prescribe this treatment for puppies less than four months old.

    Antibiotics

    • When the patches of mange appear to be infected, your vet may prescribe an oral antibiotic to help fight off the infection. Signs of an infection include red skin that looks like a rug burn or swollen areas. Antibiotics usually are topical and do risk further hair loss.

    Home Remedies

    • If you prefer to treat demodex mange at home, you do have options. However, before beginning a home treatment, you should discuss your plans with your veterinarian first to assure safety for your pet's specific situation. A mixture of 1 cup of 1 percent hydrogen peroxide with a tablespoon of borax can be used to treat the mange. Dab this mixture directly on the infected areas of your pet's body. Elizabethan collars also can be used to prevent your pet from chewing at the spots.
