Is this shell rot or something else?

The shell has been chewed on - rats, dog, something with sharp teeth.

Thank you for answering! Do you know what I could use to help with the healing?

It needs no treatment, it's superficial. . . not even as bad as a skinned knee on a human would be. He's feeling no pain, and it's not going to grow back.
