  In this study, we evaluated the therapeutic efficacy of a topical formulation of Selamectin (spot-on) against two ectoparasites: fleas and ear mites in dogs and cats. A total of 45 dogs and cats were selected and treated with Selamectin (Revolution®, Zoetis) applied to the base of the neck following the manufacturer's instructions at the recommended dosage of 6 mg/kg body weight. Treatments were administered on days 0 and 14, and efficacy was assessed based on the presence of ectoparasites (fleas and ear mites) before and after treatment. The efficacy against fleas was 71,43%, 100% in dogs, and 87,5%, 100% in cats on days 14 (after the first dose) and 28 (after the second dose), respectively. For ear mites in cats, a single dose of Selamectin completely eliminated (100%) the infestation within 14 days post-treatment.
