What do you do for a burn from a dog leash?

For a burn from a dog leash, first, gently clean the affected area with mild soap and water to prevent infection. Apply a cool compress to reduce pain and swelling, and then cover the burn with a sterile, non-stick bandage. If the burn is severe or shows signs of infection, such as increased redness, swelling, or pus, seek medical attention. Always avoid using ice directly on the burn, as it can cause further damage to the skin.
