As a professional dogsitter ( www.dogsitting.co.il ) I'm opposed to this malarkey! I'm damn opposed! These robots want nothing more to take our jobs and make us honest dog-boarders unemployed!
FYI, peroxide 3% doesn't really work. It just burns. Instead, get a 4% chlorhexedine solution. it doesn't sting AT ALL (unless it gets in the eyes) and is more effective than peroxide (though less than iodine).
