My Tripod dog has slippery floor issues--suggestions?

My Australian Shephard had her front leg amputated in May, and is getting around very well except for slippery floors. She tenses up after having slipped on them several times, and this makes it even worse. I've put as many rugs down as do-able, but that only goes so far. I thought about the sticky spray that show dog owners use, but am reluctant since she licks and washes her paws constantly. I've also used booties, but hate to leave them on full time, and putting them on and off all the time isn't really that easy. Any other suggestions? Thanks in advance!
