The difference a good set of ears makes

Sarah just arrived home from the grocery store. While she was gone, many cars drove by the house and Abe slept peacefully at the end of the couch. About 15 seconds before she arrived home, he abruptly sat straight up and turned to look at the front of the house. I, of course, didn’t know what was going on, until the garage door opened.

Apparently, Abe knows and can distinguish the sound of our car from the sound of every other car in the neighborhood. And he can do it when the car is at least a quarter mile away. Sarah had told me about this when we lived back in Illinois, but there were hardly any cars that went by our house then, so I had passed it off as some type of fluke.
Dogs are the best.
