I also want to add, that when we want Zoey to do something, we call, Zoey", first to get her attention. then the command. she knows about 15 words, and the commands and what to do. I spend a lot of time with her. some people think too much at times. but she is a love, and sleeps under the blankets with us. Backup is a command for when she's under the balankets. she know what it means.
