Bonnie wrote a good post on the subject. We have encountered giardia while camping in the mountains, specifically Sand Dunes National Monument. The problem there is the wide shallow (less than an inch deep in many places) river that flows thru between the dunes and the camp ground. Giardia, as I understand it, contaminates streams when animals pee in the stream and someone else manages to get the water in there mouth. This usually happens at the sand dunes because the river is wonderful to play in, kids, buckets, sand castles, sun, fun etc and of course you would be eating or drinking or wiping your mouth while you play in the sand. It takes a week or so, I think, before you feel the simptoms of stomach cramping and severe diahrea. In order to comfirm its presence a stool sample must be tested with a half hour and then the doctor will perscribe a medication. This all happened to a friend's daughter and they had a terrible time trying to figure out what was wrong. It is fairly common here, I don't know how you would prevent your dogs from drinking outside water if they go outside but I am sure that Bonnie's links will give you an answer. Sorry about the sick dogs, that is a real pain. Jane (off to give the cat a pill for her cough) > > Hi Rosemary - Sorry to hear about your dogs.
