Let Your Dog Sniff on Walks: Here's Why It Matters
- For dogs, sniffing stimulates the brain and relieves stress.
- Restricting sniffing on walks can increase anxiety and problem behaviors.
- Nose work is an enrichment activity you can easily start at home.
What sniffing means to a dog
Dogs understand the world through a sense of smell far more developed than ours. Sniffing on a walk is like us looking around and gathering information — a natural way for a dog to explore its surroundings.
Through smell, dogs detect traces of other animals, food and danger signals, and they also leave their own mark. It is an instinctive and essential activity.
Why you should let your dog sniff
Sniffing activates a dog's brain and provides mental stimulation. In animal behavior science, this kind of stimulation is known to be very important for a dog's mental health. As the brain works actively while sniffing, stress goes down.
Dogs that are often stopped from sniffing on walks can become more anxious and may show more problem behaviors at home, such as chewing things or barking excessively. Dogs that get to sniff enough tend to be calmer and more settled.
Sniffing also builds confidence and a sense of safety. Recognizing its territory by scent on a familiar route gives a dog emotional stability.
What is nose work?
Nose work is a mental stimulation activity that uses a dog's sense of smell. The dog finds hidden treats or toys by scent, and it is easy to do indoors. Unlike natural sniffing on a walk, nose work is an activity you design on purpose.
During nose work, dogs focus and solve problems. This helps brain development and, above all, gives your dog the satisfaction of having 'achieved' something on its own.
Starting nose work at home
The simplest way is to scrunch up a towel or blanket and hide treats inside. At first, let the treats peek out so your dog finds them easily, then gradually make it harder.
Putting treats in a box or paper bag and letting your dog dig them out is also good. Your dog naturally uses its nose and satisfies its instinct to dig at the same time.
A snuffle mat lets you do this in a more structured way: hide treats in the pockets and folds of the mat and let your dog find them by smell.
Enjoy walks and nose work together
On walks, give your dog as much time to sniff as it wants. If you plan the walk with separate 'sniffing time' and 'moving time', you can control the pace and your dog still gets plenty of mental stimulation.
At home, nose work adds extra stimulation. It is a great indoor activity on bad-weather days when you can't walk, or for high-energy dogs.
Every dog has a different level of interest in sniffing. Some sniff the whole walk, others only now and then. Respect your dog's natural behavior.
What owners often miss
If you think of a walk only as 'exercise', it is easy to cut sniffing short. But for dogs, mental stimulation matters as much as physical exercise. Even a short walk with plenty of sniffing leaves a dog more satisfied and calmer at home.
When you reward with treats, praise your dog for the smelly things it finds. This way your dog learns that sniffing itself is a fun activity.
- Start on today's walk: each time your dog sniffs, say 'Good, sniff' and give it enough time.
- Start simply at home: hide treats in a scrunched-up towel and let your dog find them.
- Reset your walk plan: plan by time rather than distance, and include sniffing time.
- 5–10 minutes a day: nose work can be short — a little every day works well.
- Watch your dog: notice how focused and happy its face and body look while sniffing.
Frequently asked questions
If I let my dog sniff on walks, won't it get out of control?
It's actually the opposite. Dogs that are allowed to sniff enough behave more calmly and steadily. It may take time at first, but once your dog learns the difference between 'sniffing time' and 'moving time', it will focus better on walks.
How often should we do nose work?
It depends on the dog. A high-energy dog can do it every day, while 2–3 times a week may be enough for a calm dog. If your dog seems tired or loses interest, it's fine to do it less often.
My dog doesn't seem very interested in smells.
Every dog has a different interest in scent. Start with a favorite treat (for example jerky or cheese) to show how fun sniffing can be. Over time, your dog will gradually show more interest.
