with 3 Yorkies here,, and one being a puppy when i got our first washablel pads,, i just put them down where their puppy pad always is,, put the paper pad on top, and did that for weeks,, and i still have more paper pads left,, but out in a storage room,, ran out in here,, and wasnt dressed to go out and get more,, so i just left it just the washable pad,, and they used it fine,, and i also have the PiPi Dolly potty, which our newest addition will use,, surely wish i could get them all to go that way,,, but i'm happy as we are now,, with the PiPi Dolly and the washable pads,, no leakage,, no smells,, i wash them ,,dry them,, run a light (empty) washer with some bleach after washing them,, and there is no smell in my washer i think they are an awesome idea!!
