Parasitic dermatitis in dogs continues to be one of the most common and clinically relevant problems in modern veterinary practice due to its high incidence and considerable influence on animal health status. This study aimed to summarise current data on the prevalence, aetiology, pathogenesis, clinical manifestations, diagnosis, and treatment of dermatitis of parasitic origin in dogs. The study employed methods of analysis and synthesis of scientific literature sources. Parasitic dermatitis was found to have a polyetiological and multifactorial nature and to be most commonly caused by ectoparasites, particularly fleas, lice, chewing lice, and mites. The leading position in the general structure of the disease was taken by flea allergy dermatitis, and acariases, which are of considerable importance due to their high communicability and propensity for a chronic course, play an important role. Clinical signs were non-specific and manifested as pruritus, erythema, alopecia, crusts and scales, and the development of complications related to the development of secondary bacterial and fungal infection, which complicated the differential diagnosis. Laboratory methods for the detection and identification of pathogens using microscopic, serological and molecular genetic methods proved to be one of the main stages in making a diagnosis. Current treatment methods are based on the use of insectoacaricidal drugs, in particular, isoxazolines and macrocyclic lactones, as well as the control of secondary complications and the implementation of preventive measures. The practical value of this study is the systematisation of current scientific approaches to the diagnosis, treatment and prevention of parasitic dermatitis in dogs in order to improve the efficiency of veterinary practice
