Feeling heartbroken, Schaffer went inside to teach. He thought the dog was reaching out for help, and told his students he needed their help keeping an eye out for him.

As soon as the school bell rang at the end of the day, Schaffer went out to look for the dog, but couldn’t find him.

But when Schaffer got to work the next day, guess who was waiting for him?

“This time he ran up to greet me,” Schaffer said. “So I just walked back to my car, calling him, and he came. I was trying to lure him using tofu from my lunch, it was all I had! Finally, I just picked him up and put him in.”
