Giardia is a protozoal organism that can infect the intestinal tract of dogs and cats.
Infection occurs when a dog or cat ingests giardial cysts in food, water, feces or soil.
The most common sign of giardiasis is diarrhea. It may be chronic or intermittent and may contain mucus or blood. Other symptoms include, weight loss, listlessness, intestinal gas or loss of appetite. Some animals may carry giardia and show no clinical signs. It is our policy to treat animals that are showing clinical symptoms of giardia.
