Summary
Thirty adult dogs with chronic generalized demodicosis were treated with oral administration of milbemycin oxime (0.52 to 3.8 mg/kg oj body weight, q 24 h). Results oj skin scrapings were used to determine whether administration oj milbemycin should be continued or discontinued. Dogs that were free of clinical signs of demodicosis 12 months after administration of milbemycin was discontinued were considered cured. Sixteen dogs were cured, 5 dogs were never cleared of mites, and 9 dogs were cleared of mites, but relapsed after administration of milbemycin was discontinued. Adverse effects of milbemycin were rare and transient.
