It's evicent that dogs have a sense of humor. In the evening as I watch the TV, every time I leave my recliner for a bathroom break or refreshments, my male chihuahua jumps up into the chair. When I ask him in a firm tone what he is doing there he turns his head and looks around as if to say "you talkin to me?" After that he returns to his favorite spot on the other side of the room. He does this as if he is taunting me. Both of the chihuahua's (MALE and Female, brother and sister) have thier own way of messing with me daily. I only wish I could hear them laugh as they do it. God made dogs mans best friend but God cheated us by not letting us hear dogs laugh.
