I would definitely get meds for all your pups!! Testing is done through a stool sample. Giardia can settle in the lower GI tract or upper GI tract. If in the lower GI tract - mucousy/bloody diarrhea will usually occur. If in the upper GI tract - vomiting. Pups can also have it and not be symptomatic. Stress will cause the giardia to multiply greatly!!!
Once diagnosed, everything the pup comes in contact with needs to be thoroughly disinfected with a bleach solutions (all toys, bowls, crates, floors, sleeping area, etc). And once a pup has had it, they are much more susceptible to getting it again. It is spread through the cysts present in feces of infected animals. Most birds are carriers, so walking over fresh or dried bird poop and then licking the feet can infect them and the spores also settle in standing water (puddles, streams, etc.).
Unfortunately, we've had two bouts of it with Sissy. One lower Gi and one upper GI. Pancur did not work for her, but a 10 day script of Metronidazole (liquid, beef flavored) worked great. When she had it two months ago, my vet also treated Angel as a precaution.
Good luck!!!
