A tapeworm in a dog is called the same thing, a tapeworm. The most common kind of tapeworm found in dogs is the Dipylidium Caninum, which is the cucumber tapeworm or double-pore tapeworm.
The tapeworm has a head called the scolex. On this head there are teeth that hook the the intestines wall. Should this fail, there are also a set of suckers. The teeth and suckers keep the worm from being digested. The body is made up of segments called proglottids, generated by the neck. With these segments the worm can grow up to 30ft long! The segments eventually break off to either find another place in the body or to come out with the feces. If it comes out with the feces, it was most likely be picked up by other creatures. The segments that remain in the body may travel up the brain, eyes, and other places such as the liver.
They are commonly called suckers.
