i don’t know if it would in your dogs case or not, but it might be worth asking your vet about using new skin (the krazy glue like liqud bandage). there are doctors using on people, so it might be worth seeing what the vet has to say. if he thinks it’s okay, i’m sure it would do a much greater job than bandages or stitches at keeping the wound from reopening as well as keeping bacteria or germs from getting in it and causing infection.
