Sophie injured her front leg and the wound is taking longer than normal to heal. The wound is about 1/2 inch long on the front of her leg. I clean it daily with pyroxide when I get home in the afternoons because she is outside a good bit (dog door). Is pyroxide slowing the healing process? I have tried tapping gause over the wound but she just chews it off. I really don't want to go with a cone because she does use a dog door and is very easiliy traumatized (abused by previous owner). Thanks in advance for your advice!
