A forum member suggested I use Nothing in Life is Free for my dogs and I had some questions about the practical implementation. Namely, what makes a trick/task "enough"? The post suggests making the dog lie down before throwing, is that before each throw or the start of the game? If it's between each throw, what if the dog does another trick like dropping the ball in the throwers hand? If a dog brings a rope to play tug, is that enough of a task or should I insist she sits first? And does it count if a dog responds to a command given to another dog?
