With our latest bout of winter weather, we've had snow that started to thaw and then re-froze, so it's an icy covered snow. The last couple of times Brady has played outside he has cut all four paws when he runs on the hard/crunchy surfaces. Nothing major, but enough that he leaves blood spots when he walks for a little while, and I can see little nicks on his pads. I've tried putting muttluck boots on him which do help except that they fly off his feet when he runs and I'm putting them back on every few minutes. Any other suggestions to help prevent this (aside from moving to a warmer climate :doh?
