Successful Management of a Recurring Canine Demodicosis in a Spayed Adult Female Eskimo Dog

Abstract

This case report describes a recurrent episode of generalized demodicosis in a 9-year-old spayed female Eskimo dog referred to the Veterinary Teaching Hospital, University of Ibadan. The dog presented with chronic dermatological lesions including alopecia, erythema, follicular pustules, and pruritus, accompanied by secondary bacterial infection. Diagnostic evaluation via skin scraping confirmed the presence of Demodex spp., while other laboratory tests showed mild hyperproteinaemia, elevated eosinophil count, and increased serum AST levels. Initial treatment with subcutaneous ivermectin (0.2 mg/kg) provided transient relief, but recurrence necessitated a more comprehensive regimen. A multimodal therapeutic approach combining fluralaner (Bravecto™), higher-dose ivermectin (0.3 mg/kg), weekly amitraz washes, and anti-inflammatory support with dexamethasone proved effective in resolving lesions. This case highlights the
importance of accurate diagnosis, sustained acaricidal therapy, and regular monitoring in managing chronic demodicosis, especially in immunocompromised or geriatric dogs.
