The prevalence and structure of parasitic diseases of dogs was studied for the first time in the conditions of Northern TransUrals. The dynamics of their parasitism was analyzed. The survey of dogs of different gender, age and breed was conductedin the period from 2002 till 2017. As a result of the research, it was found, that diseases with parasitic etiology were registered in dogs in 42.5±1.78% of cases. Significant role in the parasitocenosis of dogs is played by mites; among them there is the class Arachnidas, divided in 2 orders: Acariformes(Otodectescynotis, Sarcoptescanis, Demodexсanis,Cheyletiellajasguri) and Parasitiformes(Ixodespersulcatus, Dermacentermarginatus,Dermacenterreticulatus).As a result of the study, we obtained information about the seasonality of otodectosisin dogs; during the study period, this disease was diagnosed in 26.1 ± 1.25% of cases. The peak of otodectosis falls on the summer period - 58.33%, and the decline - for the winter period - 0.78%. The analysis showed, that the greatest peak of invasion in dogs was observed in July - 19.44%, in August - 27.78%, and in September - 19.13%. Sarcoptic mange was diagnosed in 16.4 ± 0.97% of cases. The peak of sarcoptic mange falls on the spring-summer period - 21.15%, and the decline - for the winter period - 0.57%. Demodecosis of dogs was diagnosed in 38.68 ± 1.32% of cases. The highest peak of invasion was observed in May - 10.7%, and in August - 17.2%. Among the short-haired dogs, demodectic invasion occurred in 51.1% of cases, and in long-haired dogs –in 48.9% of cases. In addition, scaly and mixed forms of demodicosis were diagnosed more often in short-haired animals;pustular and mixed forms - in long-haired animals. The analysis of parasitizing of ixodid ticks showed, that Ixodespersulcatus was revealed in 30.7 ± 1.02% of cases, Dermacentermarginatus–in 12.7±0.22% of cases, and Dermacenterreticulatus– in 56.6±1.36% of cases. Seasonal activity of ixodid ticks is very high: in spring - Ixodespersulcatus (from April to the first ten days of June), Dermacentermarginatus and Dermacenterreticulatus (from May to mid-June) and in autumn (from August to the end of September). The amount of ixodids in the biotope is directly dependent on fluctuations in the ambient temperature; the most comfortable range is from + 10°C to + 22°C. Keywords: dogs, parasites, mites (ticks), biology, modern urban environment, ecological epidemiology, otodectosis, demodecosis, sarcoptic mange, cheyletiellosis, ixodid ticks, acaricides.
