Keep the area rinsed several times a day with saline solution. If you make your own solution at home, be sure to make a new batch for each rinse. Adding a teaspoon of Epsom salt to two cups of boiling water makes an easy rinse. Always cool before pouring onto your puppy.
Pat the area dry. With each rinse, you should begin to see a healthy pink skin forming on the outer edges of the wound.
Apply a topical antibiotic or aloe vera to the skin to aide in healing and to keep bacteria from forming.
To keep the wound soft and moist and to avoid it scabbing over, cover the wound with gauze. If the wound dries out, it could scab over and cause itching.
Be sure to uncover to rinse and apply topical ointments at least twice a day. If you notice the wound getting crusty, you may need to do this more often. Observe healing and watch for signs of infection.
