ABSTRACT
Gastrointestinal helminthes in domestic dogs in Shiraz and the effect of age, sex, anthihelminth drugs, use of dog [pet or guard] and food on the infection rate were studied in 105 fecal samples. Samples were collected directly from the rectum and examined by floatation method. Data was analyzed by Chi square test and Fisher's exact test. No significant differences were found in male and female dogs and also different age groups. Higher infection rate was observed in guard dogs in comparison with pet dogs. The infection rate was higher in dogs feeding on viscera or uncooked food. The awareness of owner's about the zoonotic helminthes infection was unsatisfactory. However according to risk of communicable helminthes educational programs for owners are strictly recommended
