and I do advocate cleaning initially with antibacterial soap and water, rinsing well and pat-dry. Then I put on a medicated powder over the "wet gooey area" so that it helps form a pseudo-scab, adding more powder the next day if needed. You do want to clean a bit beyond the edges that you see...same with the medication, put it about 1/2inch beyond the margin you see as sore. Oral antibiotics may help it heal faster but she can do it on her own if you keep her E-collar on, keep watch on the hot spot that it doesn't get worse, ie, bleed or stinkly or greenish pussy discharge or swollen...and it should dry up on its own in about a week. Of course if you had antibotic powder to put on it, that would be best.
