The types of worms commonly found in dog feces include roundworms, hookworms, whipworms and tapeworms, says PetMD. These intestinal parasites affect a dog's digestive tract and, in addition to being in feces, can be found in the vomit of an infested dog.

Only roundworms and tapeworms can be seen with the naked eye; hookworms and whipworms require the use of a microscope or similar imaging device to be detected in an infested dog's feces, states PetMD. Additionally, tapeworms are rarely seen outside of the body; instead, lost segments of the worm can remain attached to the fur around the anus.

The symptoms of worm infestations can include diarrhea, weight loss, lethargy, dry hair, stomach pain or no symptoms at all, explains WebMD. The medications that veterinarians use to treat worm infestations are fenbendazole, milbemycin, moxidectin, nitroscanate, piperazine and pyrantel. Initial doses of any of these medications kill the adult worms, and subsequent doses kill the developing worms that the first doses could not.
