INTRODUCTION. Although many studies on the frequency of endoparasites in dogs and cats in Canada have been reported (Joffe et al., 2011, Can. Vet. J. 52:1323-1328), seasonal and/or annual patterns are often not extimated, furthermore very few and aged papers have been written about owned dogs and cats in Canada. MATERIALS AND METHODS. The frequency of endoparasitc infections from samples of cats (2,391) and dogs (15,016) submitted to the Veterinary Teaching Hospital (VHT) of the Atlantic Veterinary College, University of Prince Edward Island-Canada was determined, using univariate and multivariate analysis. Predictors of endoparasitism, such as sex, age, geographical origin and seasonality, were also investigated through the calculation of odds ratios (OR) with 95% confidence intervals. RESULTS AND CONCLUSIONS. Overall thirteen parasite genuses were detected, cats showed a higher frequency, with this species difference being statistically significant (χ2=15.494; P |
