Vets use surgical glue. I did a google search, some places seem to think super glue is OK on a small opening; don't want it to get inside and cause an infection.

OK on the foot pad, for foot injuries:

Just one example, and I don't know the web site to say yay or nay. Only you can see how large the opening is. Oh and one duck hunting web site said to use what you have, a regular stapller vs. a medical stapler, super glue vs. surgical glue.

Have to say, if I had a small wound on me or a pet, I'd try it!
