I am looking for some useful/fun things to teach my border collie mix. She is really smart and learns tricks really fast. She already knows the following tricks: Sit Lay Down Crawl Paw High Five Stay I have also taught her a fun game when I hide her toy and tell her to "go find" and she brings it back to me. Does anyone have any idea's as for what I can teach her? Stuff that may be helpful around the house. Like turning off the lights ect. Thank You in advance.
