The proximity between dogs and humans represents a potential risk for transmission of zoonotic endoparasites. This study aimed to estimate the prevalence of zoonotic gastrointestinal parasites in dog feces. One hundred and five fecal samples were collected and all were recorded in relation to the age and sex of the dogs to detect the presence of helminths and protozoa using a compound microscope. The overall prevalence of endoparasites was 95.23 %; the parasites with the highest prevalence were Ancylostoma caninum at 72.38 % and Toxocara canis at 49.52 %. Single infection was 43.8 % and multiple infection was 51.5 %, the most common parasitic association was between Toxocara canis and Ancylostoma caninum with 17.14 %. On the other hand, the prevalence of Toxocara canis according to the age of the dogs was 42.86 % in puppies and 6.67 % in adults (p < 0.01). In conclusion, a high prevalence of gastrointestinal parasites was observed in stray dogs, among which there is the presence of species with zoonotic importance, representing a potential public health problem, mainly affecting children.
