On the third side of the cage there was a door. I'd noticed that door before. Every day a man would come by with a bowl of food for my mother, and he'd open the door and put the food in. She would get to her feet, shake off a puppy or two, and gulp her meal down, coming back to us as quickly as she could.

This was the first time I had taken a close look at what was beyond that door. Grass. A long strip of lawn that teased my nose with the smells of moist earth and growing things. Around the lawn was a wooden fence.

It was a lot to take in. I stumbled back to my mother and settled down for a nap on top of two sisters.

The next day, when the man came by, I was paying attention. He had a bowl of food in one hand and a piece of paper in the other, and he was frowning at it.

"Yorkshire terriers, week or so" he said, looking in the cage next door, the one with puppies. Then he stopped in front of our cage and peered inside it. "Golden retrievers, probably three weeks yet, and got a dalmatian ready to pop up any day."

I could tell he was not saying those words to any of the dogs. He never spoke to us. Quickly, he opened the door of our cage. I trotted over, eager to see what that green grass might feel like under my feet. But the man pushed me aside with a grunt, not very roughly, but not gently either. He put the bowl down in front of my mother.
