Faecal samples from 224 dogs from 23 animal shelters in the Netherlands were examined for endoparasites. In total 20.5% of the faecal sample were positive for helminth and/or protozoa infections. Eggs of Toxocara canis were found in 8.5% of the faecal samples. Other endoparasites found were Toxascaris leonina (0.5%), Trichuris vulpis (4.9%), Uncinaria stenocephala (2.2%), Dipylidium caninum (1.3%), Taenia spp. (0.5%), Cystoïsospora canis (1.3%), and C. ohioensis (1.3%). Dogs younger than 1 year and stray dogs showed the highest prevalence of infection. T. vulpis was found more often in dogs from shelters with a high cleaning frequency.
