Gastrointestinal parasites in dogs from the Island of St. Pierre off the south coast of Newfoundland.

The present work was performed to survey the gastrointestinal parasites of domestic dogs (Canis lupus familiaris) and also to determine if any were infected with Angiostrongylus vasorum (French Heartworm), on the French Island of St. Pierre off the south coast of Newfoundland. A total of 57 fecal samples were collected and examined for intestinal parasites. The overall prevalence of parasitism was 57.9% and the six species found were: Uncinaria stenocephala/Ancylostoma caninum (47.4%), Toxocara canis (22.8%), Isospora canis (8.8%), Trichuris vulpis (7.0%), and Alaria canis (1.8%). There was no significant difference in overall prevalence between genders, except for T. canis, which was more common in female dogs than male dogs (p<0.05).
