Dogs tend to be scavengers by nature, and they use their sense of smell to track down all sorts of what they consider to be treasures. Why not exercise your dog's right to perform this natural dog behavior in a way that can also be fun for you?
Scavenger hunts can be a great way to get your dog out and about in different environments, having exposures to novelties he doesn’t experience at home. When done the right way, this can have a huge benefit on his confidence – dogs that mostly stay in their small "comfort bubbles" can have a tendency to be more anxious and stressed in changing or novel situations, and/or become more reactive or aggressive as a result of fear/lack of confidence. Going on a scavenger hunt provides mental stimulation too!
