How to get your dog used to a harness, part 1: Step-by-step guide and positive reinforcement
Updated 14 October 2026
In short: to get a dog used to a harness, go in small steps and reward each one: let it sniff the harness on the floor first, then have it put its head through to reach a treat, fasten one buckle, then all of them, and gradually lengthen wearing time at home before the first walks. Sessions last 2 to 5 minutes, several times a day. At the first sign of stress, go back a step.
Why some dogs dislike the harness
Having something pulled over its head, feeling straps tighten, hearing a buckle click: for a dog these are new and sometimes worrying sensations. A dog that was forced, or whose harness rubbed, may remember it badly. Habituation turns the harness into a signal for walks and good times.
The 4-step method
Click each step for details. Only move on when your dog is relaxed at the current step.
Goal: the harness means good things.
- Put the harness on the floor in its usual spot. Let it sniff at its own pace.
- Drop treats on and around the harness. Praise every approach.
- Handle the harness near it: open and close a buckle, reward calm at the click.
- Hold it over its back for a second, take it away, reward.
Goal: the dog puts its head through by itself.
- Hold the neck opening in front of it with a treat on the other side. It puts its head through, eats, you take it off.
- Lay the harness on its back unfastened for a few seconds, reward.
- Fasten one buckle, reward, unfasten.
- Fasten all the buckles, reward, take it off after a few seconds.
For a dog that dislikes things going over its head, a model that opens at the neck can help.
Goal: it forgets it's wearing it.
- Lengthen the time: 30 seconds, 1 minute, 5 minutes, while playing or at mealtime.
- Check the fit: two flat fingers under each strap, nothing in the armpits.
- Clip the lead on at home and let it trail for a moment, supervised.
Goal: harness = a nice walk.
- First outings of 5 to 10 minutes somewhere calm (garden, quiet street).
- Let it sniff: that's what makes the outing rewarding.
- If the lead goes tight, stop and wait for it to slacken. Don't pull.
- Head home before it's tired, take the harness off, reward.
- Then vary the places and lengthen the walks.
How long does it take? A few days for a curious puppy, several weeks for a fearful dog or one that had a bad experience. The dog sets the pace.
Spotting signs of stress
An uncomfortable dog tells you before it runs off or growls. If you see any of these signals during a session, stop, go back a step and make sessions shorter.
Signals not to ignore
- Yawning, licking its nose
- Head turned away, avoiding your eye, whites of the eyes showing
- Ears flat, tail low or tucked
- It freezes, backs off or rolls over
You can move on
- It approaches the harness by itself
- Loose body, tail at normal height
- It takes treats
- It puts its head through without hesitating

A comfortable harness makes it easier
A harness that's too tight or rubs undoes all the habituation work. Choose a Y model in the right size, padded and adjustable at the neck and chest, like our Comfort Y harnesses. For size, use the size calculator, then follow our guide to adjusting the harness.

Frequently asked questions
How long does it take to get a dog used to a harness?
From a few days to several weeks depending on the dog. Short, regular sessions (2 to 5 minutes, several times a day) work best.
My dog runs away when I get the harness out, what should I do?
Go back to step 1: harness on the floor, treats around it, without trying to put it on. Let it come by itself for several days.
My dog freezes in the harness, is that normal?
It's common at first; the feeling is new. Toss a treat a metre away to get it moving, play with it and keep sessions very short.
Do I need a special harness for training?
No, but a light, padded, well-fitted harness makes it easier. A model that opens at the neck helps dogs that dislike things going over their head.
