This research was carried out in two veterinary clinics in the Daule and Samborondón cantons, 100 dogs that had external otitis were sampled, two diagnostic tests were used to determine the presence of the mite, the swabbing and trichography. The registered results were: 2 % prevalence of the mite in the 100 samples performed, only the males were affected giving 3.5 % prevalence. According to the age 2.9 % of adult dogs were positive, likewise 3.1 % of geriatric dogs, positive young dogs were not reported.
