The amazing sit, down, stand game.
You will need two mats large enough for a dog to stand on, per dog.
Start with two contenders. Handler places mat in front of the dog and has the dog sit on the mat. Then handler puts the second mat in front of the dog and has the dog lie down on it. Then handler takes the first mat and places it in front of the dog and the dog must stand on it. And so on, maybe repeat twice or three times.
Rules: the dog is not allowed to move off the mat. First dog to have one or more feet off the mat, loses.
Handlers may not physsically manipulate the dog. Treats may be used.
Tips: Instead of mats, use large cardboard(like flat cardboard boxes)
Make the race all about sit, or just down, or just stand.
The barrell race:
Three targets(traffic cones, chairs, or anything you can circle around)
Handler and dog have to circle all three targets while heeling.
Tips: Handler and dog are running.
Variations: Sit at first target, handler has to circle dog while in sit, then heel to second target.
Down at second target, handler circles dog, then heel to third target.
Stand at second target, handler circles dog, dog has to stay. Handler walks away for recall.
Or any variation you can think of.
Handler and dog who complete the course fastest are the winners.
