Tapeworms are parasitic worms that tend to thrive in the dog's intestinal tract. They typically infest dogs upon accidentally ingesting a flea (its intermediate host) most likely during the grooming process, explains Dr. Eric Barchas, a San Francisco veterinarian. While tapeworms are unlikely to cause significant health issues in dogs, tapeworms are still capable of depriving the dog of some nutrients and may cause some fastidious clinical signs. Attentive and well-informed dog owners therefore may be able to confirm the presence of tapeworms by simply knowing what symptoms to look for, or, better, by inspecting the dog and the areas the dog most likely frequents for specific signs.

Presence of Segments
-
When ready to reproduce, tapeworms release segments that are basically sacs full of eggs. One of the easiest ways to diagnose tapeworms is therefore to verify the presence of such segments. Tapeworm segments resemble white grains of rice and can be found on the dog's stool, on the fur around the dog's rectal area or in places the dog frequents often, such as the dog's bedding. Upon being released, these segments are able to move a little but then eventually dry out, resembling a sesame seed, according to Mar Vista Animal Medical Center, based in Los Angeles.
Anal Irritation
-
Because tapeworm segments are released from the dog's rectum, affected dogs may suffer from anal itchiness and irritation. Their small movements indeed may cause some dogs to lick their anal area excessively or drag their bottoms on the floor or on the carpet (a behavior often referred to as ''scooting'') in order to get some relief, according to the Baker Institute for Animal Health, a part of the College of Veterinary Medicine at Cornell University, located in Ithaca, New York.
Other Symptoms
-
Occasionally, tapeworms may dislodge their attachment from the dog's intestinal wall and move to the stomach. When this happens, dogs may develop an upset stomach along with vomiting. Even though quite rare, some dogs may also become debilitated and even lose weight when the tapeworm infestation is severe and no treatment is sought.
