When Jake gets his feet dirty, I rinse them with the water hose. He lifts his feet, one at a time and I rinse them off. I have a rug at the back door and he walks across it. By the time he walks through the kitchen into the bedroom, where the carpet is, they are dry enough not to be a problem. I used to walk the springers around the steps of the pool to rinse theirs. I kind of like the boots idea. Could you take old socks and put over the foot, with a clip or something at the top. You would still have to bend over though, twice to put them on and take them off. Sorry, I don't have any good ideas.
