We have confirmed and one suspected case of giardia here at my place. Contamination source was not water, but as a result of sticking a nose where it didn't belong. I just picked up the meds from the vet for the first case and a specimen container aka poop tube for the other possible victim. We just moved into our new place and the pooper scooper hadn't been unpacked yet otherwise it would have been contained to just Whitney the new puppy.
I didn't know dogs could get giardia....................DUG
