Cookie's elbow is hurt

But, thankfully, not badly.
We noticed some blood stains on the the carpet. I looked her over and saw that he elbow was bleeding.
I had her lay down on her side, cleaned it off with hydrogen peroxide (3%). I then saw the wound clearly. It appeared to be two small puncture wounds on the callous on Cookie's elbow:
slighly Graphic.
I bandaged bandaged it.


All the while, Cookie was looking at me like "What's all the fuss about?"


Any words of advice that I could do or watch out for?
