Story says it was a 911 hang up call. That would mean the 911 operator could call back to see what happened. But if the dog made the call, the phone would have to be off the hook to dial and how how could a dog hang up the phone, anyway?

how how could a dog hang up the phone, anyway?

Story says call was made by dog stepping on phone. Probably a mobile.
