My rat terrier has some cuts on the side of her mouth, its looks like she bite herself while playing with my other dog. The cuts are serious and I thought they would heal on their own but its been weeks now and they still haven’t gone away. They start to scab over and heal but then my dog begins to chew on her lip and peel the scabs off and open the cut up again. A cone won’t help because of the location. Should I take her in? I mean I am afraid that if they give her stitches that she will just chew those off as well. Plus irs not deep or large enough to require stitches.
