TIC-TAC-TOE
Draw or tape out a large tic-tac-toe board (#) on the floor or pavement. You can use rope or spray paint (or chalk) if you are playing on the grass. Divide people up into two teams. One team is X's and one is the O's. X's go first so they have an advantage. They are the SITS. O's will be doing
Different versions: In one version, any dog who moves himself out of the position he was placed in (goes from a sit to a down, for example), is removed from the board, and that team has one less X (or O) out there.
In another version, if a dog changes positions, he STAYS in that position and becomes the other letter (from an X to an O), whereby he would be helping the other team. In a third version, handlers are allowed to cue their dogs to remain sitting, or to pop back up into a sit. They are not allowed to "correct", just to "cue." If they are going to try to fix the dog, they have to do it before the other team puts another dog out, or they lose the opportunity.
