A survey was done on 78 dogs of different ages and both sexes in Giza Governate to detect the incidence of the infestation with Spirocerca lupi in dogs. Fifty-eight cases were positively infected; only twenty-seven cases had the clinical disease with the master sign of vomiting. The characteristic Spirocerca lesions were encountered mostly in aorta, esophagus and in few cases stomach involvement was also noticed. The most pronounced P.M lesions were the tumor-like nodules in the last mentioned organs, those nodules contained cross-section of large number of the bright red worm in a yellow pus.
