Canine demodicosis is caused by Demodex canis mite found in hair follicles. Demodicosis is a nonpruritic dermatosis which frequently becomes pustular by bacterial complications. The evolution of demodicosis as clinical disease takes different aspects, from dry to festering, from a manifestation of generalized or localized to one particular. According to current research, symptoms of demodicosis are constantly changing influenced by various favourable factors, an aspect that creates confusion in clinical approach and thus prevent correct diagnosis. In this context, the aim of the study was to bring current information on clinical diagnosis in canine demodicosis. The study was performed from September 2011 to December 2014, on a total of 187 dogs diagnosed with demodicosis microscopically. Clinical signs followed in this study were: erythema (”demodectic spots”), hair loss (”demodectic glasses”), follicular keratosis, hyperpigmentation, hyperseborrhea, pruritus. We also followed the evolution of the disease forms: dry demodecosis with nummular forms (circinate) and diffuse alopecia, piodemodicosis, pododemodicosis and otodemodicosis. The results revealed the absence of typical lesions: ”demodectic glasses”, ”demodectic spots”, occurrance of hyperpigmentation and itching in dogs with dry demodicosis (untypical for this form of clinical evolution and appearance of itching, generalized erythema and alopecia as a single clinical signs evolving. Specific localizations (pododemodicosis and otodemodicosis) were diagnosed without combination with other pathogens and clinical manifestations common to several pathogenic entities (itching, ihor smell, collections ear like ”coffee grounds”, blistering interdigital). The results contribute to the complex diagnosis of one of the most common and important diseases of parasitic nature of the dog.
