I have an elderly dog on diuretics for his heart condition. He can not make it through the night with urinating, so he uses a floor pad. This makes for a smelly situation. I use the pads for humans (they are more affordable than the dog version), and they are impregnated with something to reduce the odor, but it's not enough. If there any product that would neutralize the odor as soon as the urine hits the pad?
