I have a spray-on pet bandage from 3M-I think I got it at Target or maybe PetSmart? It comes in a travel size container, and mine came in a green package on one of those cardboard things so it can hang (just to help you find it). That works well on foot pads at our house-I have used it when they have kind of skinned up their feet, and after a few days it wears off.
I would be careful with the regular liquid bandages they sell for people-some of that stuff has anti-infectants in it, and it BURNS like no other on me, I can't imagine how that would feel on a yorkie's foot
