I do it all the time. I know it bothers Dad because he tries to figure out what I’m trying to say. He is always convinced that I have some kind of serious need whenever I do it. He doesn’t know that sometimes I get bored and stare at him for the fun of it, just to mess with him. It can be a lot of fun and a good source of entertainment.
He’ll start asking me questions: What is it, buddy? Do you need to go out? Are you hungry? Do you have to go potty? Did you hear something outside? I try to look more urgent just to get to him. He figures we dogs only have a few basic needs and when I give him the stare, he goes down through the list.
