Dipylidium caninum the double-pored dog tapeworm mainly infects dogs and cats, but is occasionally found in humans. Treatment Statistics Worldwide. Human infections have been reported in Europe, the Philippines, China, Japan, Argentina, and the United States. As the tapeworm grows, pieces of it break off into segments and pass into the dog's intestines.We can find white to cream colored segments, or pieces, of tapeworm in the dog's feces or in the fur under the tail. Dogs may bite or lick the anus, or drag their hind quarters across the floor in response to the itching.
Tapeworms will be found in the anal sac or in the feces of the animal. A fecal, or stool, sample can be used to review for the presence of tapeworms. False negatives do occur, but most test results are conclusive. Precisely, 4.37% of cats were infested by a flea population infected with D. caninum. Out of the 1969 C. felis from cats, 2.23% were found to be infected with Dipylidium. From the 396 dogs infested with C. canis, 9.1%% were infested with the Dipylidium infected fleas, which is significantly higher than the observation made in cats (p=0.03). Moreover, 3.1% of the C. canis fleas were found to be infected with Dipylidium, which is not significantly different than in C. felis.
