I looked at quite a few videos demonstrating nose games and saw all kinds of interesting things. One family kept tossing boxes when their puppy took too long to find the treat. Another kept giving hints. And some of the videos are of more formal training classes with a definite intention to go onto more serious searching.
This video is a good demonstration of how beginner nose work games can look in your house.
Keep in mind, your dog’s personality will determine what the games look like in your home. Honey is a very fast and excited sniffer. And although she doesn’t do it at home, at class, every find was followed by a “victory lap” where she greets all the other people excitedly in celebration.
