Shh!

Barley, a dog, looks at a “no cell phones” sign left on a side table in a college building’s lobby.

This space has little to worry about from Barley. I’m confident that Barley can’t even conceive of telephony. Her world is very small and immediate, and (we presume) that she behaves as though the world beyond her immediate sphere may as well not exist. As such, she’s not expecting to receive any calls.
