Most dogs become infected by drinking water contaminated with feces. Giardia then infects the small intestine, and infected dogs pass microscopic cysts in their stool. These cysts can then infect another animal or person if ingested. Giardia cysts are very resistant in the environment, and can live for many months under the correct circumstances. These cysts are a threat to pet health, and giardia is a very common cause of pet diarrhea in the United States.
