When I see a person with a dog I try to say something nice. If I'm in Petsmart I try to say "Hi, cutie" or "Hi, doggie". I try to find something nice to say about the dog, what a pretty color, what a shiny or fluffy coat, such lovely eyes. If it's a long line and the dog seems okay with it, I might ask the person if I may pet their dog for a moment. I thing God must have had a fun time creating dogs - now a fluffy one, now a sleek one, now a big one, now a small one ... You get the idea.
