Hello Ladies! Please excuse me if I'm posting this in the wrong area but, I hope some of you can give me some insight. My 8 week old puppy has Giardia and my vet has told me it is contagious, if I come in contact with his stool. Recently I've been extremely careful when he uses the restroom but a couple weeks ago when he pooped, I accidentally got some of his poop on my arm but immediately washed it off, and washed my hands.
