What Are the Treatments for Demodex Mange on Dogs?

Commonly called the red mange, this disorder is a result of a microscopic mite that penetrates the surface of the dog's skin, destroying the fur in patches. Demodectic mange is more common in puppies but an older dog with an immune disorder may also develop the problem. Demodex mites live in a dog's hair follicles and pass from the mother dog to her puppies by direct contact in the first few days of their lives, usually causing no adverse problems. When demodectic mange develops, your veterinarian may order various treatments.

  1. Insecticides

    • A mild form of demodectic mange results in thinning fur patches, often located on the dog's face, and it frequently resolves itself. However, the topical application of canine-safe insecticides may hasten the healing process. Shampoos, ointments or sprays containing Rotenone, such as Goodwinol Ointment, are applied to the dog's fur and re-growth of hair is seen in approximately one month.

    Antibiotic

    • Your vet may recommend a topical antibiotic solution if the hairless patches appear reddened or swelling is present. However, rubbing the ointment on demodectic mange patches may break weakened hairs at the base and result in further temporary hair loss.

    Clip and Dip

    • Although your dog is not actually dipped into anything, the application of amitraz (Mitaban), a monoamine oxidase inhibitor (MAOI), is applied to the dog's body when demodectic mange spreads beyond a localized area. Amitraz is generally restricted to use on puppies over four months of age. Your vet may clip or shear away your dog's fur in the affected areas before applying amitraz. A side effect of this treatment may cause drowsiness.

    Anti-parasite

    • Oral anti-parasite medication, such as Interceptor, may be used to control demodex mites if your dog suffers from recurring infestations. This medication is given monthly for heartworm, but your vet may recommend a daily dosage.

    Home remedy

    • EarthClinic.com reports that a possible home remedy for localized demodectic mange can be made by combining 1 tbsp. of Borax to 1 cup of 1 percent hydrogen peroxide solution. If your peroxide is a 3 percent solution, dilute it with water at the ratio of 1 part peroxide and 2 parts water before adding the Borax. Dab onto your dog's coat with a sponge and do not rinse out. Consult your veterinarian if you have any questions about mixing this solution and discontinue use if your dog exhibits any side effects.
