Tamar teaches Oprah to use hide-and-seek to teach her dogs to follow the sound of her voice. Soon, Layla comes when Oprah calls!
Tamar cautions against using the dog's name too often—you should only address them by name when you want their attention. "You teach them that when you say their name, it's worth it for them to listen to you," Tamar says. "If you go all day and you say, 'Luke, Gracie, Layla,' and you're not talking to them, they're going to tune you out."
