Authors studied the seasonal invasion of yard dogs by socially dangerous bio- and geohelminths on the territory of the Republic of Kabardino-Balkaria. In the Republic of Kabardino-Balkaria, during all seasons of the year, domestic dogs are the source of 9 zoonotic species of helminths, such as Metorchis bilis, Echinococcus granulosus, Dipylidium caninum, Mesocestoides lineatus, Toxocara canis, Ancylostoma caninum, Dirofilaria repens, Dirofilaria imitis и Trichinella spiralis for a person. Quantitative indicators of the extent of invasion caused by socially dangerous helminths of the species Metorchis bilis, Echinococcus granulosus, Dipylidium caninum, Mesocestoides lineatus, Toxocara canis, Ancylostoma caninum, Dirofilaria repens, Dirofilaria imitis и Trichinella spiralis ranging from 13.33% to 60.00%. In autumn, in domestic dogs, socially dangerous helminths of the species Metorchis bilis, Echinococcus granulosus, Dipylidium caninum, Mesocestoides lineatus, Toxocara canis, Ancylostoma caninum, Dirofilaria repens, Dirofilaria imitis и Trichinella spiralis were recorded with large amounts ranging from 6.67% to 40.00%. It was established that in populations of yard dogs, the most frequently recorded species of socially dangerous helminths of zoonotic etiology in all seasons were Echinococcus granulosus, Toxocara canis, Ancylostoma caninum.
