Stealth
With a dog, hiding and seeking isn’t the greatest game. Why is that? Because they would sniff you out and find you every time. All you have to do is teach him to WAIT before they begin looking for you. On the other hand, they are terrible at remaining hidden.
To them, if they can’t see you, they’ll assume you can’t see them as well. They’ll extend one leg and stand up straight with the body completely visible, making you wonder whether they were truly hiding. Dogs are unaware of how to properly employ their surroundings and the significance of things like camouflage.
