Canine Demodicosis, commonly known as red mange or follicular mange, is a challenging ectoparasitic refractory skin disease affecting dogs. It stems from the excessive proliferation of Demodex spp mites within hair follicles and occasionally sebaceous glands, precipitating dermatological disturbances. This review delves into the intricate facets of Canine Demodicosis, exploring its causes, manifestations, and impact on affected canines. The disease manifests when these mites colonize hair follicles and sebaceous glands, leading to a spectrum of presentations from localized to generalized demodicosis. The latter is characterized by pronounced dermatological alterations encompassing erythema, alopecia, follicular hyperkeratosis, pustules, and crusts across the body. The condition is often further complicated by secondary pyoderma, exacerbating its severity [5]. In severe instances, generalized demodicosis poses a potentially life-threatening risk, emphasizing the need for early recognition and intervention. Intriguingly, Demodex mites are not exclusive to afflicted dogs, with a prevalence of 5.4% even among ostensibly healthy canines. This highlights the complex interplay between mite presence and disease development. The canine demodicosis landscape is sculpted by three key Demodex species: Demodex canis, the most prevalent; Demodex injai, characterized by a robust physique; and Demodex cornei, distinguished by a shorter stature, approximately half that of D. canis.
