I've used bleach for years,I have never had an issue with dogs pads,I make up a good drop,( a cup full roughly)into a bucket of water,stir vigorously and lash it all over after the shits picked up,never a problem with feet,I use a squeegee to take as much water as I can from the floor surface....but the chlorahydrate (chloras) is a different matter,you need to be careful with that,
