Choose safe sniffing places
Use grass verges, tree bases, and open ground where you can see litter and other dogs. Avoid broken glass, treated lawns, traffic edges, feces, and unknown food. Sniffing is valuable only when the location is safe.
Give enough leash for the dog to lower the head and investigate without wrapping around signs, people, or shrubs. A fixed leash is easier to manage in a tight neighborhood than a long line.
Sniffing can reinforce a loose leash, but it does not replace the basic walking rule. If your dog reaches every smell by pulling, first work through the complete stop pulling plan, then use access to selected sniffing spots as the reward.
Teach a clear release
Approach a familiar sniffing spot. While the leash is loose, mark the moment, say “go sniff,” and move with your dog to the spot. After several repetitions, the phrase predicts permission to explore.

Do not pull the dog away after one second. Let the reward be real. When it is time to continue, say a separate walking cue and reward the first step back with you.
Use sniffing without creating a tug of war
If the dog surges, stop before reaching the scent. The instant the leash softens, continue. You are not withholding all sniffing; you are showing that pulling does not make the destination arrive faster.
Mix planned sniff releases with unstructured sniffing. A dog should not have to earn every ordinary smell. Save the formal routine for spots that strongly motivate pulling or for short training sequences.
Match the walk to the dog
Some dogs prefer food, movement, distance, or social contact to sniffing. Watch what your dog chooses. A reward only works if the dog values it in that moment.

On a decompression walk, sniffing may be the main activity. On a focused training walk, short sniff breaks can keep the outing balanced.
When sniffing changes suddenly
Persistent ground licking, eating nonfood objects, or a sudden inability to disengage deserves closer observation. Move away from hazards and contact your veterinarian if the behavior is new or comes with vomiting, appetite change, or other symptoms.
For ordinary pulling between scent spots, use the loose leash guide rather than removing sniffing from the walk.
Keep the reward practical
Decide before the walk which places are safe for longer investigation and which require a brief pass. This prevents a confusing pattern in which the dog is sometimes pulled away and sometimes allowed to stay at the same spot. A release cue should add clarity, not control every second of the outing.
Watch the leash while the dog sniffs. Step closer instead of holding tension from several feet away, and reposition before the line winds around a tree or leg. Call the dog away while there is still room to move, then reward the turn back toward you.
