They are Toxocara canis,Ancylostoma coninum, Dipylidium conium, Taenia hydatigena, Isospora canis andClonorchis sinensis.2. Intestinal parasite infection rate is59.32%.3. The infection rates for every canine with parasite species are different.Infection rates of Toxocara canis, hookworm, Dipylidium caninum Taeniahydatigena, Isospora belli and Clonorchis sinensis were53.80%,22.62%,25.86%,47.91%,7.98%and2.09%, respectively.4.121cases were infected with two kinds of intestinal parasite synchronously,the rate was23%;98cases were infected with three kinds of intestinal parasitesynchronously, the rate was18.63%.5. Occurance of parasitic infection are different in ages, parasitic infection inpuppies was higher than that in adult dog; occurance of parasitic infection aredifferent in environments, parasitic infection of dogs rearing outdoors was higher thanthat indoors.6. No correlations were observed in the dog's species and gender in the intestinalparasitic infection.7. Effect of IVOMEC (1%ivermectin solution) on Toxocara canis was observed.The best result was obtained at the dose of0.5mg/kgBW subcutaneous injection for twotimes interval seven days.
