Intestinal parasites of well-cared-for dogs: an area revisited

A prior study (1970) of parasites in fecal samples of 846 dogs recovered from an area in the Edgewater and Rogers Park areas on the far North side of Chicago showed 13.7% of the fecal samples to be positive for one or more parasites. A pilot study of 200 fecal samples in the same area in 1979 revealed that 21.5% were positive. An additional 606 fecal samples were then observed for a total of 806 samples in 1979-1980. A prevalence of 23.4% was shown in the specimens collected in 1979. A study of 110 fecal samples from the Chicago dog pound revealed a prevalence of 71.8%.
