Otodectes Cynotis"Otodectes Cynotis is caused by a mite infestation in the dog ear. Your veterinarian will prescribe a miticide and the area where the dog lives should be cleaned with a miticide as well" Dog ear mite infestations look as if there are coffee grounds or debris in the ear canal. Ear mites are large, white and freely moving with four pairs of legs extending beyond the body. The ear mite life cycle lasts 3 weeks. They lay eggs with a type of cement which sticks it to the ear. After 4 days of incubation, a 6-legged larva hatches and feeds for 3 - 10 days, then rests a day and hatches to the protonymph (8 legs, last pair very small) and later molts into the deutonymph. This disease is curable when a miticide is applied (something that kills the mites) with excellent results.

TreatmentYour veterinarian will use anti-parasitic agents such as ivermectin to treat this condition. If your vet suspects that your dog has a mite condition, then a topical ointment that kills mites (miticide) will be recommended.To ensure that the environment where your dog lives is free of mites use a cleaner specifically designed for killing mites such as Benzarid.
