Parasites are a common problem in dogs. They can become infected with roundworms, tapeworms, hookworms, and heartworms. Worms are nematodes and create a vicious cycle of reproduction, reintroduction and subsequent infection. Hookworm larvae can live inside of a host -- your dog -- for several weeks until maturity. Your dog will shed the parasites in his feces. Canine hookworms will lay more eggs, which perpetuates the cycle.

The nematode’s mouth literally “hooks” itself to a dog’s intestinal tract or skin. Intestinal hookworms feed on the dog’s blood. Dogs of any age or breed can become infected with hookworms.

The test is called a “fecal float” because the fecal sample is combined with a drop of water. The fecal float is a highly reliable test. Your veterinarian will also perform an extensive exam of your dog to make sure he isn’t suffering from any other conditions caused by hookworm infestation.

You can also have your dog dewormed on a regular basis, depending on where you live, how frequently your dog is outdoors or if he is in regular contact with unfamiliar dogs. Pet owners can also help break this cycle by cleaning up after their dog when out walking or playing in a public area.
