Amazing what they pick up on, and how they use it! Salty started calling our dog Tinker, when she was alive, in my wife's voice. He did it to mess with the dog's head, calling her into another room all the time. He continued doing it after she passed, much to the annoyance of my wife. Salty still does it occasionally, even after Geri has passed, i guess to try and get a rise out of me.
