I think she knows me by "mama" and my bf as "daddy" because she gets so excited when my bf knows i'm almost home and he says "mama's here" and she gets so excited and runs to the door (and vice versa).
For Brutus I am Grandma. (even though he is truly my dog, he is supposed to be my sons dog!) and Frankie i'm mommy. If I say to Bruty, Grandpas home, he runs to the door to greet my husband.
Me-Mommy, I call myself that to him and Joe call's him momma's boy. Joe is known as daddy- when he pulls in the driveway after work I say "daddy's home" and Vegas runs to the door waiting for him. Now since Joe did his anals the other night, and I did his tail pocket the night before that, I am positive Vegas has come up with some "choice" words for both of us. lol
