According to the American Veterinarian Association, roundworms, which are an intestinal parasite, are the most common parasite found in dogs and cats. Infection occurs when the larvae, which are found in the animal's feces and soil, are ingested by another animal or human. If left untreated in people, roundworms will enter the lungs, brain or liver, which can cause health complications. If the condition is left untreated in dogs or cats, roundworms can cause blockage in the intestines, and if the intestines rupture, it can cause death.

Diagnosis of Roundworms
-
If you suspect your dog has roundworms, talk to your veterinarian about conducting a screening for this condition. Symptoms of this condition include vomiting, loose stools and weakness. Your vet will request a feces sample and evaluate the sample for eggs. If your dog tests positive for roundworm, you'll need to medicate him immediately to get rid of the infection.
Medications for Roundworm in Dogs
-
There are several medications used for roundworms, including Hartz Advanced Liquid Wormer, Heartgard Plus and Interceptor. Talk with your dog's doctor about which medication is best for your dog. After the initial worming, your dog will need to be wormed again in a few weeks to get rid of remaining larvae. Once your dog is "worm free," talk with your vet about using a year-round preventive treatment, and provide a fecal sample a couple times a year to prevent future outbreaks.
Roundworm in Humans
-
If your dog has roundworms, be diligent about hand washing; especially for young children. Symptoms of roundworms in humans include vomiting, problems sleeping and worms in vomit and stool. Medications used in humans include Mebendazole and Pyrantel.
Preventing Additional Outbreaks
-
Roundworm eggs are resilient and survive in soil for months, and even years. Discourage your dog from ingesting soil, and make sure to be diligent about preventative medications.
