I own two dogs, and they both have been trained to respond to my voice. For example, when we're outside, all I have to do is issue the following command: "Here Earnest! Here Zippy! C'mon! I said come HERE! You dogs COME HERE RIGHT NOW! ARE YOU LISTENING TO ME? HEY!!!" And instantly both dogs, in unison, like a precision drill team, will continue trottin in random directions, sniffing the ground.
