I don't know if you saw my post with my leg xrays, but if you did you would know that my front legs are a bit wonky. Aside from all the other issues, I have a permanent limp on my left side. Part of my left wrist joint is fused and so when I walk two of my nails drag. They get really short and if I walk too much on pavement they some times hit the quick and bleed. My mom used to use duct tape but then she found these cool caps (they're called Soft Paws). They work great - my nails have grown longer underneath them!
