tapewormTapeworms got their name because they are thin and flat, like strips of tape. Unlike the smooth-bodied roundworms, hookworms, and whipworms, tapeworms' bodies are actually made up of joined segments. Tapeworms are common parasites that live in the small intestine of dogs, cats, and other animals and they steal the nutrients from the food eaten by the animal. Dipylidium caninum, the most common tapeworm of dogs and cats, is transmitted by fleas. Dogs and cats become infected with this tapeworm by ingesting fleas during self grooming and licking. Two other types of tapeworm are also very common: Taenia pisiformis in the dog, and Taenia taeniaeformis in the cat are transmitted by rabbits and rodents (mice, rats, squirrels). Dogs and cats become infected after ingesting one of these infected animals.

The adult tapeworm consists of a head and a very long body. The body is made up of many segments. Some of the segments (called proglottids) break off and are passed in the feces. The proglottids are cream colored and are often seen attached to fur around the animal’s anus. The proglottids of D. caninum are very mobile and crawl around the animal's anal area. This produces an itching sensation and may cause the animal to "scoot" across the floor.

Tapeworms are diagnosed by identifying the proglottids. These segments are about the size of a grain of rice and are found in the pet's bedding, attached to the fur around the anus, or in the feces.

Tapeworm infection rarely causes noticeable clinical symptoms. A voracious appetite is sometimes observed as well as a slight decline in body condition.

Medication is available for treating tapeworm infection. The medication kills the adult worm. After successful treatment, segments are no longer seen in the feces.

Flea prevention is an excellent method of controlling D. caninum infection. Consult your veterinarian for more information on how to effectively rid the flea infestations. Taenia infections are controlled by reducing the pet's contact with intermediate hosts (rabbits and rodents).

Tapeworms are rarely a risk to people.
