When I was young and telephoning BBSs was a thing, our dogs kept chewing up
the telephone lines under the house, rendering my extension inoperable. I
have no idea what the dogs' fascination with the phone line was, but to get
it working, I'd have to crawl under the house and patch or replace what
they'd chewed. I even left the old wire down there so maybe they'd chew on
that instead (no such luck). During one of my repairs, we had a call come in
and I can assure you it's not nothing, especially if it's unexpected.
