When you can't go out, the brain does the work. Five simple games that tire more than an hour of running.
How we do it in the pack
We always start with short sessions in a calm place, with rewards the dog really wants. When it goes well, we raise the difficulty little by little: more distance, more time, more distractions. When it goes badly, we take a step back with no drama.
Always finish with an exercise your dog already knows. Ending on a success is half the work for the next session.
