Ouch, poor Omi! Gently wash the wound warm water and antiseptic soap. To keep her from licking at it, you can put an Ecollar on her. You can get one at a pet store or make one at home. Keep the wound clean and dry, and monitor it for signs of infection. If you see redness, swelling, warmth to the touch, or pus, then it is infected and she will need to see the vet for antibiotics to treat it. I hope this helps!
