harness, or does she wear the dog's?

There is a blind guy who works across the hall, and he and his service dog often come and visit us (my colleague is an animal lover, and even had dog treats in her desk).

He and his dog just came by and were talking about how he and his wife went out to dinner last night, and didn't take the dog with them...

I almost make the joke, but my better judgement won.

I had to tell it.

Thank you for listening, I feel better.
