When we think of play for a dog, we imagine a ball, a race, a tug-of-war. But there's a silent and invisible activity that means much more to a dog: sniffing .
Sniffing is more than a gesture: it's a true form of communication with the environment, a mental activity, a primary need. It's how dogs "read" the world. It's no surprise that a dog's quality of life is closely linked to the freedom to use their nose.
Smell, their superpower
A dog has between 200 and 300 million olfactory receptors (compared to our 5-6 million). The part of the brain responsible for processing odors is about 40 times larger than that of humans. It's not just a matter of quantity: dogs are able to distinguish odor molecules in infinitesimal concentrations, even when mixed with thousands of others.
For example, they can recognize the scent of a single individual who passed by a meadow hours earlier, distinguishing it from all the others.
Smelling is a cognitive activity
We often underestimate how tired a dog can get, not just by running, but also by working with his brain. And smell is the main way a dog does this. When a dog sniffs a new area, he's not just walking: he's analyzing, memorizing, comparing information , and developing a complex mental scenario.
Olfactory activities are therefore stimulating and tiring, but in a positive way: they are satisfying, calming, and improve concentration. In highly reactive or anxious dogs, daily olfactory exercises bring tangible benefits within a few weeks.
Smell and emotional well-being
Scent activity reduces the production of cortisol (the stress hormone), stimulates serotonin, and helps dogs find balance. This is why scent games are used in behavioral therapy, in managing phobic dogs, in hyperactivity situations, and even in old age to keep the brain active.
Sniffing slows the heart rate, relaxes the muscles, and helps the dog "return to himself" during times of stress. And it offers a form of mental freedom that is often denied.
Olfactory games: a world to rediscover
Scent enrichment can (and should) be part of every dog's daily life. There's no need to invest in expensive professional tools: all you need is imagination, patience, and attention. Here are some practical suggestions, organized by context:
At home:
– Hide treats or kibble in cardboard boxes, old towels, or piles of pillows.
– Create olfactory trails in the hallway or in the garden with different smells (spices, aromatic plants, objects passed by other animals).
– Use scent rugs or make your own using an old knotted blanket and hidden treats inside.
During the walk:
– Choose new routes, vary your locations. Even small changes make a difference.
– Allow long stops: if the dog stops for minutes to “read” a trail, let him do so.
– Bring scented objects with you to introduce along the way to stimulate further searches (balls, ropes, old clothes).
Relationship Games:
– Create a treasure hunt for two: hide treats while the dog watches, and then give him the lead to find them.
– Introduce commands like “search!” or “sniff!” to build dialogue during the game.
– Reward calmly, letting the activity be rewarding in itself, without excessive excitement.
Mistakes to avoid
– Don’t interrupt your dog while he’s sniffing just because he’s “not walking.”
– Avoid overly complex scent games at first: the dog must succeed to avoid becoming frustrated.
– Don't confuse olfactory activity with alimentary activity: the goal is to use the nose, not just obtain food.
Smell as a bridge between us and them
Letting your dog use his nose means respecting his nature. But it's also a way to connect more deeply with him: observing how he moves, what interests him, how he calms down after a good search.
It means slowing down, listening to its rhythms. Making room for a communication that doesn't come through words, but through sensations, pauses, and shared choices.
Sniffing is living, really
A dog that can smell is a calmer, more fulfilled, and freer dog. Incorporating olfactory activities into your daily routine isn't just a pastime: it's a gift of well-being, respect, and understanding.
And perhaps, by slowing down with him, we too will begin to observe (and smell) the world with different eyes.
