My ACD, Rocky, loves to learn new tricks. We were part of a doggie line dancing group for a while and among other things, he learned to circle around me backwards and bow. To get attention he finds a small blanket, spreads it out and covers up in it. When the grandkids come I give one of them a bandana to hold out of sight, I sneeze and tell Rocky to go find me a hanky. Of course, he gives them all the once over (to squeals of delight!) until he finds the one with the bandana. When he brings it to me he gets a treat.
