Move the Clip. Change the Walk. | Trueline
Move the clip. Change the walk.
The leash ring sits at the center of his chest, not between his shoulder blades. When he pulls, he turns toward you instead of dragging you forward.
- Padded mesh across the chest and belly
- Four adjustment points and a quick-release buckle
- 30-day fit guarantee: the right size shipped free if the fit is off
- Ships with tracking. Most orders arrive in about 2 weeks. Some take up to 4 weeks.
Why the leash goes tight in the first place
Most harnesses clip the leash between the shoulder blades. When a dog leans into a back clip, the pressure on his chest tells him to lean harder. A dog pushes back against pressure. That is why a 50-pound dog can tow a grown adult down the block.
He pulls, it goes straight
The ring sits behind his shoulders. Every pull points him forward, and your arm takes the load.
He pulls, he turns
The ring sits at the center of his chest. A lunge swings him sideways, toward you, so there is nothing to lean into.
What is on the Trueline
A simple harness with the clip in the right place and a fit you can adjust to your dog.
A harness is a tool. Here is the free method that goes with it.
You can start this today, with no harness at all. It takes about five days of short walks to see how your dog responds.
- Stop when the leash goes tight.The moment it tightens, stand still like a tree. Do not tug back. Wait for slack.
- Reward the slack.When the leash loosens, even a little, say "yes" and give a treat at your side, not out in front.
- Change direction.If he keeps surging, turn and walk the other way. He learns that going forward only works when the leash is loose.
- Start somewhere boring.Practice in the driveway or a quiet street before any place with squirrels, dogs or smells.
- Keep it short.Five or ten minutes of this beats an hour of tugging. End while he is still doing well.
A front-clip harness makes step one easier on your arm and shoulder while he learns. It does not train him for you.

Find his size
Measure around the widest part of his chest, just behind the front legs, and match it to the chest column. If he is between sizes, go by the chest measurement. If the fit is wrong when it arrives, we ship the right size free.

CHOOSE SIZE AND COLORQuestions
Will it stop him from pulling?
A front-clip harness changes the leverage, so a pull turns him toward you instead of pulling you forward. It makes loose-leash walking easier to teach, but he still needs practice. Use it with the five-day method above.
