When I brought maddie home, the first night i noticed the bloody/mucous stools, took her to the vet, it was giardia, it was a nightmare. she was put on flagyl, i was able to get liquid version, i put her in the bathroom with a baby gate until treatment was done, when she stooled i cleaned it immediatly, i whiped her bottom with babywhipes, after ten days of that she still had loose stools and was positive, so another ten days of meds, and by the way these meds cause them to not want to eat so i had to force feed with a syringe every few hours because at 16wks she was only 1lb 2oz. They also contract it from other infected dogs stools, it does lie dormant in the intestional lining and stress such as a new home "activates" it. So in a nutshell good hygeine, clean stool immediatly with a spray bleach, whipe your puppies nose and paws and make sure your dog is eating and drinking, sorry this was so long
