How to clean dogs wounds

1 Diagnose the wound. One of the most common problems dogs have is called a "hot spot." They will lick it often, and the hair will begin to disappear around it. Sometimes it has pus and blood around it.
2

Clip the hair from around your dog's wound to allow you to see it and clean it properly and let the wound heal without any hair getting stuck to it. Scissors will work, but clippers are better.
3

Clean the wound with a mild soap and warm water, and be sure all the soap is rinsed out. Gently pat the area dry.
4

Pour hydrogen peroxide on the wound, or dab it on with a cotton ball several times a day. It's not a problem if your dog licks at it a little. Whenever your dog goes outside, clean the wound as soon as he comes back in and reapply the hydrogen peroxide.
