krazy glue works pretty much the same as liquid stitches, my mom was pre-vet (similar to pre med training) and she used that to fix my dogs head when it fought a much larger dog and had a huge tooth mark hole in its head. its non toxic too, so that would've worked.
My local ER is actually really fast, maybe because I'm the only one ever in it. but I'm always in and out in under an hour
