After going on a hike the other day, I was checking out Chico's feet and I noticed that his toenail was extremely short. It's completely frayed at the end and his quick is hanging out. It looks pretty weird but he doesn't seem too worried about it. I trim his nails a little every week so it wasn't even long enough to hit the ground. I have no idea how it got this way. Also, the last two times we've gone hiking, Chico's gotten cut on his toes. He doesn't even notice it but there's usually alot of blood. I check to make sure that nothing is in the skin. I don't know if there is something I can do to toughen his paws. He runs on gravel in our backyard every day so I'm not sure what the problem is with his paws. Any advice would be appreciated! Sorry about the ugly pics......I swear I cleaned his feet immediatly after taking these!
