Ivermectin for Mange in Dogs

Dog mange can be treated with the dewormer Ivermectin.

Ivermectin is a commercially produced systemic antiparasite drug. Ivermectin can be given orally, usually with a struggle because it tastes terrible, or injected, according to the website marvistavet.com. Ivermectin kills all parasites in and on the dog including the scabies and demodectic mange mites. Demodectic mange mites are one of the common causes of mange in dogs. The use of Ivermectin does has some limitations and will not work with all dogs. Consult a veterinarian for the appropriateness of the treatment.

Diagnosing Mange

Mange is caused by parasitic mites while allergic dermatitis is caused by allergies. Both look similar on the dog, with a loss of hair, intense itching and scabs on the skin. Mange may respond to Ivermectin while dermatitis will not. Veterinarians may take skin samples to determine if parasites are present.

Ivermectin as a Test

According to the website vetinfo.com, a possible test for mange is the application of a dose of Ivermectin. If the skin conditions clear it was likely a form of mange caused by mites of some type. If the skin condition remains it is likely an allergic reaction, and further diagnosis and treatment is necessary.

Ivermectin as Treatment

Ivermectin is not approved by the Food and Drug Administration for treatment of mange. This means there are no published dosages from the manufacturer for treatment. Many veterinarians and dog owners do use Ivermectin for an "off label" treatment of mange and other parasites in dogs. Consult a veterinarian for dosage and treatment protocol.

Dog Breeds

Some breeds of dogs and some mixed-breed dogs have a genetic mutation that causes them to be unable to take Ivermectin. Breeds affected include many of the herding breeds and some of the sight hounds such as collies, shelties, German shepherds and whippets. Veterinarians may order genetic tests or start with small doses to determine if your dog is in danger of an adverse reaction to Ivermectin.

Cautions

Follow all instructions from your veterinarian when administering Ivermectin; overdoses can be fatal. Monitor the dog, especially after the initial dose, for any signs of adverse reactions. According to the website regalwise.com, lethargy is a mild reaction, while dogs with a moderate reaction often end up in a coma. However, Ivermectin is safe if used appropriately. It is the active ingredient in most heartworm preventatives.
