I recently stumbled upon a fascinating study from the Horowitz Dog Cognition Lab that explores how nosework—a scent discovery-based activity—can positively influence a dog’s emotional state. The researchers used a cognitive test to evaluate how quickly and confidently dogs will approach an unknown stimulus. In animal behavior science, a fast approach toward something unknown is interpreted as a sign of “optimism,” suggesting a more positive state of being.

The study itself involved twenty healthy pet dogs of various breeds and ages, divided into two groups. All dogs were first trained to associate one location with a food reward and another with no reward. Then, a bowl with unknown contents without a strong scent was placed between the two, and researchers measured how quickly each dog approached it.

Over two weeks, the experimental group participated in daily nosework sessions—structured scent-searching exercises both in a class as well as at home. The control group was involved in similar levels of physical activity and owner interaction but with any nosework.

The results were striking: dogs in the nosework group were more likely to approach the unknown bowl suggesting a more optimistic and curious outlook. The control group that did not do any nosework showed no such change. 

From my own experience using scent as an enrichment activity for shelter dogs, I couldn’t agree more. I have seen scent engage shelter dogs mentally and physically which ultimately sparked noticeable behavioral changes. One shelter dog I worked with, who was very hesitant about going outside, is now super excited to go out for her next scent adventure!

If you are looking to enrich your dog’s life, consider integrating olfaction-based activities into their routine. It’s a simple, joyful way to support their emotional health—and maybe yours too.
