Treatment
Deworming medication, by The U.S. Army
If your dog or cat has intestinal parasites, you'll want to consult your veterinarian for safe and effective treatment options. Some over the counter products can cause cramping and other discomforts, and can carry severe risk when used with animals that are too young, too old, or debilitated. The products available through veterinarians are safe and convenient, and often protect against multiple types of parasite.
