How to Identify Parasite Worms

There are a number of different ways to identify parasite worms. You can identify them by becoming familiar with the way common parasite worms look or you may browse through images online. The most common types of parasite worms in dogs include hookworms, tapeworms, roundworm, whipworm, and heartworm. Hookworms, tapeworms, roundworms, and whipworms live in the dog’s intestines and heartworms live in the dog’s heart and in the blood vessels that lead from the heart to the lungs.

To identify parasite worms, you can begin by looking for dog worms in your dog’s food, on or buried in your dog’s fur, around his anus, around his paws (from scratching), and it is not uncommon to find them in your dog’s ears. Roundworms look like spaghetti and tapeworm segments look like grains of rice.
