Parasites come in many different species and forms and can live both inside and outside your pet. Some of the more common types of internal and external parasites include:

Internal parasites:
Intestinal (GI) worms

• Roundworms
• Hookworms
• Tapeworms
• Whipworms

The whipworm is one of the four most common intestinal parasites of dogs. Whipworms reside in the cecum, which is inside your dog’s body where the small intestine and large intestine meet.

Dogs become infected with whipworms by swallowing infective whipworm eggs in soil or other substances that may contain dog feces.
