This study was carried out on 124 dogs between February 2018 and November 2018 to determine the prevalence of gastrointestinal helminths in stray dogs in Van. Collected stool samples, after macroscopic examination, were examined by native, flotation and sedimentation methods in terms of eggs and larvae. According to the results of the study, 43 (34.68%) of 124 dogs were detected as infected with various types of helminths. The most common species were respectively Toxascaris leonina (16.13%), Toxocara canis (12.90%), Ancylostoma caninum (5.64%), Taenia spp. (4.84%), Dipylidium caninum (3.22%), Uncinaria stenocephala (3.22%), Capillaria spp. (3.22%), Fasciola hepatica (2.70%) and Dicrocoelium dentriticum (1.35%) 35.14% of the female dogs were infected with parasites, while this rate was 34% for males. Statistically, infection status in males and females does not differ significantly by gender (Chi-Square: 0,17 p >0.05). When the distribution by age is examined, it is 0.5-2 years with the highest rate of 45.3%, 2-6 years with 27.7% and 5-9 years with 25%. According to age, infection status does not show a statistically significant difference (Chi-Square: 4.64, p> 0.05). As a result, it was concluded that the subsi substantial presence of zoonotic helminths in straydogs in the province of Van poses a threat to human health and protective measures should be taken againstit.
