Abstract:
Efficacy of ivermectin at a dosage of 0.2 mg/kg of body weight was evaluated against naturally acquired ear mite (Otodectes cynotis) infestation in commercially raised ranch foxes (Vulpes fulva). Efficacy of ivermectin given sc twice at 3-week intervals was 97.4%. Toxicosis associated with drug treatment was not observed. Increased dosage of 1.0 mg/kg was given sc to 5 foxes each week for 6 consecutive weeks, and signs of toxicosis or illness were not observed after treatment.
