What Is Nose Work For Dogs?

Did you know that nose work games for dogs can improve their mood and behavior?
Have you ever wondered why your dog seems anxious or bored when left alone? Or maybe you've noticed that after a long day of work, your pup is bouncing off the walls with pent-up energy? Believe it or not, the way your dog uses their nose could be the key to making them happier and more relaxed. A new study has shown that giving your dog more opportunities to sniff and use their nose (called "nose work") can improve their emotional state, making them more optimistic and calmer. In this blog post, we'll explore how nose work can benefit your dog and you, based on the results of this study.
What Is Nose Work For Dogs?
Nose work is a fun activity where dogs use their sense of smell to find hidden treats or objects. In this study, dogs in the experimental group practiced nose work by searching for hidden food rewards, while the control group did heelwork (obedience training where dogs walk beside their owners). Both groups were given the same amount of physical activity, but the key difference was that the experimental group used their noses to find food, while the control group didn’t.
How Nose Work Affects Your Dog's Emotional State
When dogs use their noses, it’s not just about sniffing out a treat. It taps into a natural foraging behavior that makes them feel more fulfilled. In the wild, dogs and other animals spend a lot of time foraging for food, which means sniffing and searching. This foraging behavior is deeply ingrained in them and essential for their well-being.
In this study, researchers tested how nose work affected dogs’ emotional states using a test called the “cognitive bias test.” This test measures whether a dog is feeling optimistic or pessimistic. An optimistic dog is more likely to approach new situations or objects with a positive attitude, while a pessimistic dog might be more fearful or hesitant.

The Study: Testing Cognitive Bias In Dogs
At the beginning of the study, dogs were given a cognitive bias test to see how they reacted to an ambiguous stimulus (something they hadn’t seen before). The dogs were then divided into two groups: one group practiced nosework for two weeks, and the other group did heelwork. After the two-week period, the dogs were given the cognitive bias test again to see if their emotional states had changed.
Here’s what the study found:
- Nosework improves optimism: The dogs in the nosework group showed more optimistic behavior after two weeks of nosework. They were quicker to approach the ambiguous stimulus in the cognitive bias test, which suggests they were feeling more positive and less anxious.
- Heelwork didn’t change emotional state: The dogs in the heelwork group didn’t show any change in their behavior. This suggests that while physical activity is important, it’s the mental challenge and natural behavior of using their noses that really made a difference in the nosework group.
Why This Matters for Your Dog’s Welfare
You might think of your dog as a family member, but in some ways, they live a restricted life. Unlike humans, dogs can’t choose how they spend their day. They rely on us for everything—food, exercise, playtime, and mental stimulation. Many dogs spend hours alone at home, which can lead to boredom, anxiety, and even destructive behavior.
This study shows that allowing dogs to engage in nose work can improve their mood and behavior. It’s more than just a game—it’s an opportunity for dogs to do what comes naturally to them. By letting your dog use their nose to search for treats or toys, you’re giving them a sense of purpose and fulfillment.

How Does Nose Work Benefit Dog Owners?
Nose work doesn’t just benefit dogs—it helps dog owners too. Here’s how:
- Less anxious, more relaxed dogs: Dogs that regularly engage in nosework are less likely to be anxious or destructive. This means less stress for you when you leave your dog alone, and a calmer household when you’re home.
- Better behavior: A mentally stimulated dog is a well-behaved dog. By giving your dog an outlet for their energy and natural instincts, they’re less likely to engage in unwanted behaviors like chewing on furniture or excessive barking.
- Stronger bond: Nosework is a great way to bond with your dog. It’s a fun activity that you can do together, and your dog will appreciate the time and attention you’re giving them.
- Easy to do at home: The best part about nosework is that it’s easy to set up at home. You don’t need any special equipment—just hide some treats around the house or in the backyard and let your dog sniff them out.
How To Get Started With Nose Work For Dogs
Ready to try nosework with your dog? Here are a few simple steps to get started:
- Start small: Hide a few treats in easy-to-find spots around your home. Encourage your dog to use their nose to find the treats. You can use verbal cues like “find it!” to get them started.
- Gradually increase the difficulty: As your dog gets better at finding treats, start hiding them in harder-to-reach places. Try putting them under cushions, inside toys, or in different rooms.
- Use scent work toys: There are special nosework toys and puzzles, like The Busy Blanket, designed to challenge your dog’s sense of smell. These can add extra layers of difficulty and keep your dog entertained for longer.
- Make it part of your routine: Just like regular walks, nosework can become a daily part of your dog’s routine. Try to set aside some time each day for sniffing games, whether it’s indoors or outside.
Conclusion: Why Nose Work For Dogs Is a Game-Changer
The results of this study are clear—allowing your dog to engage in nose work can make them more optimistic, happier, and better behaved. It’s a simple activity that taps into their natural instincts, providing mental stimulation and a sense of accomplishment. Plus, it’s easy to do at home and benefits both you and your dog.
By adding nose work games for dogs into your dog’s daily routine, you’re not just giving them a fun activity—you’re improving their overall well-being and making life better for both of you. So why not give it a try? Your dog will thank you for it!
