Dog in the mall

Just had to make note of the fact I ran into a dog INSIDE the mall. I suppose it was a service dog in training. It was a small dog (bull dog looking). The reason why I'm even talking about it is because it's the first time I've encountered a service dog that stood up and looked at me with an "I'm watching you!" kind of expression. Usually service dogs continue to lie (if that's what they were doing when I see them). I'd never seen one get up and stand next to their person. If I ever had to have one, I'd want mine to do that.
