The common kind of tapeworm is normally made up of several segments, each containing its own reproductive organs.

The segments, which looks like grains of rice, break off and can be seen in a dog’s feces. Adult tapeworms may reach lengths of about 30 inches.


Roundworms resemble pieces of spaghetti and are common in puppies. Roundworms live in the digestive tract of dogs where they feed on the passing nutrients and thus irritate the linings of intestines. Several roundworms can lead to blockages and diarrhea.

Infected puppies can exhibit a dull coat, appear restless and develop a pot-bellied look if the infestation is very much severe. Roundworms in dogs may grow to about 6 inches in length.
