How is tapeworm infection diagnosed?
An infection with Dipylidium is usually diagnosed when the white, mobile segments are seen crawling on your dog or in the stool. Tapeworms are not usually detected by the routine fecal examination performed by the veterinarian. Because of this, veterinarians depend on the owner to notify them of possible tapeworm infection in the dog.
Echinococcus infections are harder to diagnose than the tapeworm caused by fleas because the segments are small and not readily seen.
How are the tapeworms treated?
Treatment is simple and, fortunately, very effective. A drug which kills tapeworms is given, either orally or by injection. It causes the tapeworm to dissolve within the intestines. Since the worm is usually digested before it passes, it is not visible in your dog's stool. These drugs should not cause vomiting, diarrhea, or any other adverse side-effects.
Control of fleas is very important in the management and prevention of tapeworm infection. Flea control involves treatment of your dog, the indoor environment and the outdoor environment where the dog resides. If the dog lives in a flea-infested environment, reinfection with tapeworms may occur in as little as two weeks. Because the medication which treats tapeworm infection is so effective, return of the tapeworms is almost always due to reinfection from the environment.
How do I tell tapeworms from pinworms?
Tapeworms and pinworms look very similar. However, contrary to popular belief, pinworms do not infect dogs or cats. Any worm segments seen associated with dogs are due to tapeworms. Children who get pinworms do not get them from dogs or cats.
Echinococcus tapeworms are of more concern. These tapeworms cause very serious disease when humans become infected. Hunters and trappers in the north central United States and south central Canada may be at risk for infection by this worm if strict hygiene is not observed. Rodent control and good hygiene are important in preventing the spread of this disease to humans. As with the more common tapeworm, infection with Echinococcus is infrequent but possible.
