A. Roundworms are the most common worm among dogs and cats. They live in the stomach and intestines and will pass out with the faeces. They can be up to 8 inches long and look slightly like spaghetti, sometimes curled up and sometimes straight.
Pets usually ingest the larvae from the soil or via an intermediate host such as ingestion of an infected rodent. A heavy infestation in puppies can cause serious illness and can even be fatal, so it is important to check all dogs and cats regularly.
Depending on where you live, the prevention and treatment medications may vary and you should always purchase them from your veterinary practice, as they are the most effective treatments.
