What Does a Canine Roundworm Look Like?

Canine roundworms are a common parasitic infection in dogs and puppies. Although the infection is common, it can cause serious medical complications and must be treated immediately. It is important to know what canine roundworms look like and how they should be treated.

  1. Identification

    • Canine roundworms are small parasites that live in dogs' intestines. The roundworms typically enter the dog in egg or larvae form through their mother's milk. The dog may also consume roundworm-contaminated dirt or feces.

    Life Cycle

    • After they are swallowed, the canine roundworm eggs hatch inside the dog's stomach. The larvae then travel to the stomach, the liver and the lungs, where they are coughed up and re-swallowed. At this point, they travel to the intestines where they continue to grow and lay eggs.

    Appearance

    • Adult canine roundworms look similar to short, thick strands of spaghetti. They typically grow to a maximum length of six or seven inches.

    Symptoms

    • Dogs with roundworms often develop a potbelly, unhealthy coat, vomiting and diarrhea. If left untreated, an infection of canine roundworms can lead to intestinal blockage or rupture. A roundworm infection is particularly harmful to young puppies.

    Treatment

    • Speak with your veterinarian regarding an appropriate method of treatment for canine roundworms. Treatment is typically quite simple and effective; however, treatment is typically only aimed at killing adult roundworms, so it will be necessary to administer repeated treatments for any larvae or newly hatched eggs.
