Schaffer had to get to work, so he squeezed past the Lab mix and went inside. But he was so haunted by the scared and sick-looking pooch, he went back outside later to check on him.

Unfortunately, the dog was gone. Schaffer heard that someone had called animal control, but the officers could not catch the dog.

But when Schaffer got to work the next morning, the dog was there again, waiting in front of the school doors. He seemed to instantly recognize Schaffer.

“He was a lot happier to see me,” he said. “I started noticing how bad his skin was and how much it was torturing him. He was constantly scratching and whining. I felt bad, there was nothing I could do before school.”
