Teddy peels skin off his pads all the time. There seems to be a big difference between skin peeling off and actually ripping the pad open. He has done both. When the skin peels off he doesn't seem to notice other than he tries to pull the loose skin off himself. I do have winter booties for him because in the winter he gets cuts that bleed but when the skin peels off there is no blood and no raw area. Just the same black skin that was under the first layer. I often wonder if it is normal for them to lose layers of skin off their feet. I say cut the extra off and then just keep it clean. Teddy continued to play day after day after the skin peeled off and it hasn't gotten worse and no more peeled off so keeping it clean should be enough. Although I wouldn't let her run on cement for a bit.
