An abrasion does not fully penetrate and only involves the outer layer of skin. Small, uninfected wounds can be attended to at home. Large, infected, or multiple abrasions should be treated by a veterinarian. Use warm water or saline to flush out the wound. Flush enough to remove all dirt and debris from the area. Keep the wound clean and dry, and discourage your pet from licking at it (you may need to pick up an Elizabethan collar from your veterinarian). Monitor the wound for increasing pain, redness, or a pus-like discharge. If any of these occur, the animal should be seen by a veterinarian.
