On the last day of his life, my dog Otto spent that morning of spring napping in the garden. This was always one of his favorite things to do, even before the days when he was too old and too weak to get out of a car by himself.

I probably would have started crying over Otto right then, if my two other little dogs hadn't suddenly raced past. Larry, who was a puppy, got knocked into Otto, then licked Otto's ear, and that got Otto excited, and Otto barked and tried to stand up again, but it was hard for him.

Soon it was time for me to drive to see Steve, our vet.

When Steve gave Otto the first shot, it made him woozy (眩晕的). Otto wandered over to where Steve and I were sitting and settled down between us. He has always liked to touch everyone in his pack, if possible, while he sleeps.

After Steve gave him the last shot and Otto stopped breathing, he didn't look like Otto anymore. He looked like an old gray-brown piece of beat-up carpet, and I suddenly realized what bad shape he'd been in for a long, long time. I wondered if he'd been in much more pain than I knew. Wondering made me feel even worse.

The week after Otto died was not good. Every morning when I walked Larry and Sticky in the neighborhood, somebody would come up and say they had heard about Otto and they were sorry. They were all Otto's friends and some of them cried. Others, like Debbie who lives on my street, reminded me about how, even at the end. Otto would stand between her twins' stroller (婴儿车) and the street when the garbage truck went by. "Like it was his job to protect them," she marveled.

Otto has left us, but his memory lives on.
