The super glue is a good idea. I know that some vets and doctors are using it to close small incisions.

But Do not ever use Gorrilla glue or leave that product where any pet might get into it. There was a news story out of Seattle were this small maltese I think it was, knocked it off the counter & licked about 2 tsp of this stuff. Later the dog becomes very ill. The owner rushes the dog to the vet, she tell the vet what had happened. On the x-ray it show a very, very large mass. The vet calls the number on the glue bottle, Which btw has important message about pets & small children. They gave her information on what it does. She had to do emergency surgery & remove 4lbs of gunk! It mixes with the stomach juices and grows and grows.

Back to the nail... I just saw at pet smart a product made by 3m it is called
3M Pet Care skin & paw crack care.
Maybe that would work as well.
