Bleach is not a good idea for your dog to wipe their feet on...over time they can become toxic from the bleach, it will absord into their paws...washing the floors with dulted bleach once or month is fine but dont let them back in before it dries... I have mentioned Odoban many times here...it is a great disinfectant even kills HIV...you can get it in sams club, walmart, some home depots or on the internet.

"Detergents and disinfectants" are so commonly used at home can produce pus-infected skin injuries in the pads when walking on floors that are wet with these substances. The ever so common "bleach", besides being corrosive, is also a powerful toxic if ingested, like all the detergents and is effective in the minor scale, which produce salivation, depression and vomiting. According to the sensitivity of the animal, it can be more serious.
