Giardia is a parasitic infection that occurs in dogs and cats. It is characterized by diarrhea and loss of weight. Giardia attach to a dog or cat’s intestines, which disrupts the absorption of nutrients causing pale, foul-smelling greasy stools.
Giardia is passed from animal to animal by the ingestion of cysts that are shed in an infected animal’s feces. Giardia is often treated with a dewormer such as Panacur or SafeGuard for 5 days and then repeated again in 10 days.
