Q. I have a 6 week old puppy with demodex mange EHST is the protocol for using ivermectin with this age puppy

Answered By
DR. CHRISTIE LONG, D.V.M., C.V.A.

A. Many dogs have genetic sensitivities to Ivermectin that cause them to have serious reactions to even normal doses of this drug. For this reason it is only available in the U.S. By prescription and should only be used under the specific instructions of a veterinarian. Also, demodex can be very difficult to treat, and often requires repeated treatments until it resolves. In addition dogs can have secondary bacterial skin infections that require treatment with antibiotics in order to get the skin completely clear.

I'd also mention that demodex in young puppies, if it's confined to a small area and not generalized, typically resolves on its own or with topical therapy. Consult your vet to see if treatment is even necessary for what your puppy has.

A. When your vet diagnosed this they should have provided treatment advice, ring your vets office for clarification on dosage. If he has not been definitively diagnosed I would not recommend starting ivermectin on an assumption at 6weeks of age as many of the options are not recommended this young unless absolutely necessary. There are safer alternatives
