Can your dogs tell time? Two of ours can. Charlie sleeps in our bed. At nine AM and not a minute sooner, she's awake, licking my face and ready for me to begin my day. Whatever mood I go to bed in, I begin my day laughing.
Pooh knows her bed time. Each night around 1, regardless of what else is going on, she heads to bed. She's also the first one awake but is quiet until Charlie's up.
My daughter sent the photo above. Every weekday evening, 10 minutes before her husband is expected home from work, her 2 guys move to their spot at the top of the landing and wait for dad. It's uncanny. Dad was late the day the photo was taken and the guys were becoming restless.
