Please help I am so panicked. A friend brought over a shelter dog and stayed the 2days/1night with me, the dog defecated several times in my yard, I believe I got it all picked up (no diarrhea). Now I am told the dog has giardia (but it was non shedding giardia whatever that means). I am so worried about this and looking it up online panics me when I read all the problems it can cause. My vet said as the dog was only here such a short time she would prefer to test my dog's stool in a month vs treating him in case he has it. Thanks for any thoughts on this.
