As a younger dog, he rushed the doors, both front and garage. Guests entering the house had to slide in quickly before he barreled past them.
But at least a couple of times he found his way out of the fenced backyard into the great beyond. One time he moseyed under the deck and squeezed through an opening we never thought could accommodate him. I found him calmly sniffing the hedges near the front stoop.
His most likely point of departure, though, was through the backyard gate, which is tricky to latch and was prone to being left open by the meter-reading man and other folks. We lived in fear that we'd forget to check, let him out the backdoor and that would be the end of it. Copper, of course, had no fear of cars.
This week I've walked through the backyard gate dozens of times. And every time, not just out of habit but out of reverence, I've made sure it's closed behind me.
