Painfully Slow

As I drove past the park today, I saw a man walking a retired racing greyhound. He was walking, not speed walking, not jogging, or sprinting, or running, just walking. The dog looked liked she was putting much effort into staying by his side, to the point of being painful for her to go so slowly. I could see her muscles ripple with each step. She would start to trot for a second, but had to stop, or risk being ahead of her man. It was unnatural for her to walk so slowly, but she aimed to please her man. If his goal is to exercise his dog, at that pace, he's going to have to walk all day long, and then I still don't think she will be the least bit tired.
