Why You Should Let Your Dog Sniff on Walks
Sometimes the best part of a walk isn't the walking - it's the sniffing.
Many dog owners have experienced it. You set out for a brisk walk, only for your dog to stop every few metres to investigate a blade of grass, a tree trunk or a patch of sand. While it might feel like your dog is slowing you down, or hasn’t understood the fitness buddy brief, they're actually doing something incredibly important for their physical and mental wellbeing.
Recent research continues to highlight just how valuable sniffing is for dogs, with studies showing that opportunities to explore their environment through scent can improve welfare, reduce stress and provide important mental enrichment.
A dog's nose is extraordinary
Dogs experience the world very differently to us. While humans rely primarily on vision, dogs gather most of their information through smell.
A dog's nose contains up to 300 million scent receptors, compared with around six million in humans. The area of their brain dedicated to processing smells is also proportionally much larger than ours, allowing them to detect scents that are far beyond our capabilities.
Every sniff tells your dog a story. They can learn:
Which dogs have recently passed by
Whether another animal was male or female
If an animal was healthy or stressed
Whether wildlife has been nearby
Changes in the environment
What looks like "just sniffing" is actually your dog reading the neighbourhood newspaper.
Sniffing is mental exercise
Physical exercise is only one part of keeping your dog healthy!
Mental stimulation is equally important, and sniffing is one of the easiest ways to provide it.
Just as solving puzzles keeps our brains active, allowing dogs to investigate interesting scents gives their brains plenty to process. Many behaviourists describe sniffing as a natural form of enrichment that helps satisfy an important instinct.
A dog who has had a good opportunity to sniff may often come home feeling just as content as one who has completed a much longer walk.
Sniffing may help reduce stress
Recent studies have found that allowing dogs to engage in scent-based activities may help improve emotional wellbeing and reduce stress.
Dogs allowed to investigate their surroundings at their own pace often appear more relaxed than dogs continually hurried along.
For some dogs - particularly those who are nervous, anxious or reactive - sniffing can help redirect their attention away from potential stressors and encourage calm, exploratory behaviour.
Rather than viewing every walk as a fitness challenge, it can be helpful to think of some walks as "sniff walks", where your dog is encouraged to explore rather than cover distance.
Great for puppies
Puppies are constantly learning about the world around them.
Allowing them to safely sniff different environments helps build confidence and exposes them to new experiences in a positive way.
These experiences become part of healthy socialisation and can contribute to raising a well-adjusted adult dog.
Wonderful for senior dogs
As dogs age, arthritis or reduced mobility may make long walks more difficult.
Fortunately, older dogs still benefit enormously from getting outside and using their noses.
Even a shorter walk filled with opportunities to sniff can provide valuable mental stimulation without placing excessive strain on ageing joints.
Every walk doesn't need to be fast
Many owners understandably focus on covering a certain distance or reaching a step goal, but your dog's goals are usually quite different.
Instead of marching from point A to point B, consider letting your dog set the pace for part of the walk. You might find they spend several minutes investigating one particularly fascinating scent before happily moving on.
The walk becomes an opportunity for exploration rather than simply exercise.
Safe sniffing
While sniffing is beneficial, there are still situations where caution is needed.
Keep your dog on lead in areas where there may be:
Snake activity
Poison baits
Toxic mushrooms
Jellyfish
Dangerous plants
Wildlife nesting areas
Busy roads
Prevent your dog from eating unknown objects while investigating scents, and always supervise closely.
Other ways to encourage natural sniffing
You don't need a long walk to provide scent enrichment.
Try:
Scatter feeding kibble in the grass
Hiding treats around the garden
Using snuffle mats
Puzzle feeders
Beginner scent games at home
Safe bush walks with plenty of natural smells
These activities engage your dog's nose and brain while encouraging natural behaviours.
Every dog is different
Working breeds, sporting dogs and scent hounds often have particularly strong instincts to investigate smells, but every dog benefits from opportunities to explore their environment.
Some dogs may prefer long adventures, while others are happiest wandering slowly around the local park.
The important thing is allowing them time to use one of their greatest senses.
The takeaway
Next time your dog stops to sniff that interesting tree, try resisting the urge to hurry them along.
Those few extra moments may be providing valuable mental stimulation, reducing stress and making the walk far more rewarding than simply covering distance.
