I refer to my dogs as my kids, or babies. My recall command with Bella is "Bella kid, come my kid!" yes it's that, not shorter, not different, it's always that. When I want to call both Leo and Bella at the same time it's "Come kids!" Leo's recall is normal-ish "Come-it the Leo" I don't know why, it's just that. However as much as I refer to them as kids, I am NEVER mom. It's always something like "whose my cute little babykins" never whose moms pretty baby etc. however, my mother will always say "Bella get to your mother's room right now!" or if I speak to someone who knows my dogs name but not my name like most of the people at the Rottie club I will phone them up and the conversation is like "Hi there XXX it's Alicia, Bella's mom."
