Clinical and Diagnostic Findings in Dogs Infected with : A Retrospective Study.

is a parasite of the large intestine of canids and has a global distribution. Despite its well-established epidemiology, the question of its pathogenicity in dogs remains debated. It has been suggested that younger age and concurrent infection with may be responsible for more severe clinical presentations. This retrospective study aimed to describe the clinical and diagnostic features of -infected dogs and to compare these findings with dogs infected with both and other intestinal parasites (poly-infected dogs). Forty-five dogs were included, with twenty-five being solely infected by and twenty poly-infected dogs. Only weight loss was more frequent ( = 0.006) in poly-infected dogs compared to mono-infected dogs. No significant differences were observed in laboratory abnormalities between mono-infected and poly-infected dogs. Only diarrhea was more frequent ( = 0.007) in younger dogs compared to adults. The egg shedding pattern was significantly higher ( = 0.04) among adult dogs compared to young ones, and there was a significant positive correlation between egg shedding and age (r = 0.41; = 0.005). These findings suggest that might be responsible for both clinical signs and laboratory abnormalities in dogs, irrespective of the host's age and the presence of other intestinal parasites.
