Searching is what a dog’s nose is for, and doing it properly is unusually good for them: it is tiring, it lowers arousal rather than raising it, and it builds confidence in dogs who have none.
It also needs no space, no equipment, and no other dogs — which is why it suits reactive and anxious dogs better than almost any other activity.
Why it works
Sniffing is cognitively demanding. Research on nosework has found lowered heart rate during searching and, in one well-known study, more optimistic responses in a cognitive bias test in dogs given regular scent activities.
The practical effect: a dog who has searched for fifteen minutes is tired and calm. A dog who has chased a ball for fifteen minutes is tired and wired.
Stage one: find the food
Start absurdly easy. The goal in week one is a dog who understands that searching pays.
- Put your dog behind a door or ask someone to hold them
- Place five treats on the floor of a room, in plain sight
- Release them with a cue — “find it” — and let them hoover
- Repeat, gradually placing the treats less obviously: beside a chair leg, under the edge of a rug, behind a cushion
Do not help. Let them work. The moment you point, you have taught them to watch you rather than to use their nose.
Stage two: boxes
- Line up three or four open cardboard boxes
- Put a treat in one, while the dog is out of the room
- Release with “find it”
- When they find it, praise calmly and reset
Then make it harder: more boxes, boxes in different rooms, boxes turned on their sides, a treat in a box inside a box.
Stage three: a target scent
This is where it becomes a proper activity. Instead of searching for food, the dog searches for a specific smell and is paid when they find it.
Common target odours in formal nosework are birch, aniseed, clove and gun oil. At home, a few drops of a scented oil on a cotton bud in a small perforated tin works.
- Pair the odour with food. Present the tin, feed. Twenty times. The smell now predicts payment
- Hide the tin somewhere easy with food on top of it
- Remove the food from the hide and pay from your hand the moment they indicate
- Build difficulty — higher hides, lower hides, outdoors, in vehicles, in a room with distractions
The indication is whatever the dog offers naturally when they find it: a freeze, a stare, a sit, a nose push. Reward whichever they do consistently rather than trying to impose one.
Stage four: harder searches
- Containers — a line of boxes or bags, one with the scent
- Interiors — a room, with the hide at different heights
- Exteriors — a garden or a car park, where wind moves the scent plume
- Vehicles — around the outside of a car
Wind and air currents are what make outdoor searches interesting. A dog often picks up a scent several metres downwind and works back along the plume, which is worth watching.
Games that need nothing at all
The muffin tin. Treats in the cups, tennis balls on top.
Towel roll. Kibble spread on a towel, rolled loosely.
The cup game. Three cups, a treat under one, let them choose. Most dogs stop watching your hand and start using their nose within a few rounds.
Hide the toy. For dogs who are more toy- than food-motivated.
Trail laying. Drop a line of treats across grass, gradually spacing them further apart so the dog follows the scent path rather than individual treats.
Hide and seek with yourself. Someone holds the dog, you hide, they find you. Excellent recall practice disguised as a game.
Who benefits most
Reactive dogs. No other dogs involved, no social pressure, and the activity itself lowers arousal. Many reactive dog programmes now use nosework as a core component.
Anxious and fearful dogs. Searching builds confidence because the dog succeeds repeatedly at something they are naturally excellent at.
Dogs on restricted exercise after surgery or injury. A search in a hallway meets mental needs when physical ones cannot be met.
Senior dogs. The nose ages better than the joints.
Working breeds in pet homes, with more brain than their routine uses.
Puppies, as an easy introduction to using their brain and to working independently.
Practical notes
- Use the day’s food allowance, not extra treats
- Ten to fifteen minutes is a full session. Searching is tiring
- Let them fail and keep trying. The persistence is where the value is
- Do not correct a wrong choice. Simply reset
- End on a success
- Watch, do not help. Hand signals and pointing teach a dog to look at you instead of using their nose
Going further
Many areas have nosework or scentwork classes and competitions, run at several levels. They are unusually welcoming to difficult dogs, because dogs work one at a time and wait in cars or crates between runs.
For an owner with a reactive dog who has been excluded from group classes, it is often the first activity they can do together in public — and that is worth a great deal beyond the enrichment itself.
