The objective was to determine the frequency of gastrointestinal parasites in dog feces from the Jamapa shelter, Veracruz. The feces of 230 dogs were analyzed in a cross-sectional convenience sampling that lasted from March to July 2023. The samples were taken from the rectum of the animals and were analyzed in the Parasitology laboratory of the “Torreón del Molino” ranch, FMVZ of the Veracruzana University. The techniques used were: Mc Master, Flotation and modified Faust. The analysis was carried out using the STATA program; A general frequency of 98.7% was determined; independently the frequencies were: <em>Trichuris</em> spp. 16%; <em>Giardia</em> spp. 19.5%; <em>Strongyloides</em> spp. 28.2%; <em>Uncinaria</em> spp. 34.7%; <em>Toxocara</em> spp. 57.3% and <em>Ancylostoma</em> spp. 81.7%. The general frequency was similar for both sexes. Regarding age, all groups presented a frequency greater than 95%. It was determined that there is a high presence of gastrointestinal parasites in this shelter, which could pose a risk to Public Health.</p> R. M. Reyes-Sandoval Dora Romero-Salas A Cruz-Romero Y.
