Have you been treating your yard? Chances are she is re-infecting herself. *if no symptoms, why treat?* simply because giardia is contagious to humans as well. Every time she has a BM she is shedding spores. It is an intestinal parasite of sorts so why would you not want to do everything you can to get rid of it? Both of our dogs got it when we moved to a new home....this was bavk in May or June. We almost lost our senior dog to it....our yorkie barely had any symptoms of it....we medicated, cleaned all bedding, toys and kennels and treated our yard with D-Earth as directed by our vet....we did this for 2 months on a weekly basis and they have since tested negative. We still treat the yard with D-Earth on a regular basis and we do sprinkle it over their food.
