There are now three demodex mite species recognised on the dog. There must be other immunological factors involved and many people are working in this area to find the answer. The alternative theory is a hormonal change in the host causes mites to breed. The mites then carry bacteria into the follicle.
Mites are sensitive to the reproductive cycle of the female dog.
In late pregancy the mites proliferate and move to the skin surface in readiness to pass to the new born pups. The advent of the endectocides Ivermectin, Milbemycin and Cydectin has helped a lot. The most effective regime would appear to be daily dosage of these products for at least 60 to 90 days, combined with at least 1 month full dose of an oral antibiotic.
