I had a dog wrap its leash around my ankle about 3 days ago its three-quarters around my leg and is very deep. Its getting worse and throbbing and burning. Also there is a large red circle way around the deep burn. I don't know if there was feces on the leash or just dirt and stuff... I have been cleaning it with soap and water, hydrogen peroxide, and then putting neosporin on it. Its very deep, and don't know what my next step should be since it just seems to be getting worse, very deep and red, my leg is also very hot. Any ideas?

Your next step should be to see a medical provider.
