Hot Spot Remedies

Have you tried cayenne and salt on the hot spots? Never had one with the problem, but from what I understand it is an infection, or gets to be one, with bacteria and puss. The cayenne should heal it and take away any pain, so he doesn't play with it, and the heat would probably stop him from licking it, except for a chihuahua.)) I put it on cold sores as soon as they show, and it seems to stop them from continuing. It should if they contain a virus.
