Dogs can tell time. Sometimes better than their attendant humans. How do they do that? They know when it is time for breakfast, they know when it is time for dinner. And they know exactly, like down to the minute, when it is time for their treats in between. Out here in the desert it is often daylight both when you get up and go to bed, so you need clocks and watches. Yet dogs have neither clocks nor watches, how do they always know what time it is?
