I was just going to sit on my sofa today and my yorkie moved to the side and hurt himself. He cried and is sitting on his bed depressed right now. It looks like a nail wants to come out of his feet and I don't know what to do. Should I try to cut it off or just let him heal it naturally- I feel like a horrible mother because I don't know what I can do for him- the injury doesn't look that bad but the nail does look like it wants to come out.
