Canine demodicosis, also known as demodectic mange, is mainly caused by Demodex canis. It causes both localized and widespread (generalised) skin infections in dogs all throughout the world. An adult male dog (one-year-old), weighing 15 kg was presented to Veterinary clinical complex, Izatnagar, Bareilly. The animal had history of anorexia, alopecia, dehydrated, erythema, itchy skin, crust formation, hyperpigmentation, and dullness. On clinical examination and skin scrapping examination it was diagnosed as demodicosis (Demodex canis). The case was treated with tablet Bravecto (fluralaner 1000 mg) once a day orally for two weeks, along with antibacterial, antifungal and supportive nutritional therapy. The dog reacted well to medication, and no further notable side effects were observed. The third week of treatment marked the full recovery. The current report's goal is to educate pet owners about the prevalence of Demodex canis and its therapeutic care.
