How do vets test for giardia in dogs?
Giardia organisms can sometimes be identified using fecal flotation, but some veterinarians prefer to use a different test, called a SNAP test, to screen for Giardia. The SNAP test detects Giardia antigens (proteins produced by the parasite) in the fecal material of infected pets.
