Backing out is a slack problem, and this harness lets you set the slack twice

“My dog backed out of a standard harness.” One owner wrote that on a dog forum.

The name of this harness has the words escape-proof in it. Read that as the aim, not as a test result. No harness earns the word if it hangs loose.

Here is how a dog gets out of any harness. Picture a wet evening and a cat on the fence. He plants his front feet, drops his head and walks backward. A loose strap rides forward over his shoulders, and he is free.

Here is what this design gives you. The neck strap and the belly strap shorten separately. A thick neck does not make you loosen the belly, and a deep chest does not make you loosen the neck.

That makes slack easier to take out. It does not make slack impossible. A Frenchie who has backed out of two harnesses already should be fitted, tested indoors and kept away from traffic until he passes the test further down this page.

Nothing goes over his head, and the leopard is only on the panel

Lay the harness flat on the floor. You see a padded panel with four arms. Two arms carry a long strap that ends in a plug. The other two end in a socket with a round red button.

Nothing is joined until you close it. Lay the panel across his back. Bring the upper strap around the base of his neck and click it shut. Bring the lower strap around his ribs, behind the front legs, and click that shut.

Two clicks. His head stays out of it, and so do his paws. If he plants his feet and refuses to lift one, you do not have to move them.

Here is everything on the harness.

Both straps have slide adjusters. You set the neck first, then the belly, one after the other.

Look at the photos again. The print sits on the panel. The straps, the handle and the buckles are black, and so is the lining against his coat. If you wanted leopard from end to end, this is not it.

Leopard is tan with dark brown rosettes. Camo white is white with dark green and black blotches. Red, blue, purple and pink are one flat color each.

Six panels, one harness underneath. All six use the same two sizes and the same chart below.

Chest picks the size: S closes at 42 to 52 cm and M at 52 to 62 cm

Here is how to measure. Wrap a soft tape around his body just behind the front legs, at the widest point. Keep it flat against his coat and snug, with no slack and no squeeze, then read the number as it is and look it up in the chest column. Nothing gets added, because the range in the chart already holds the room.

The two fingers come later, once both buckles are shut on him.

It takes two people and one treat. One holds the treat at his nose so he stands still. The other keeps the tape flat, not twisted, and snug enough that it stays put.

Look at where S ends and M begins. S stops at 52 cm and M starts at 52 cm. There is no gap and no overlap, only the one number where they meet. A tape of exactly 52 cm goes to M, because a harness can be taken in but not let out.

Some charts leave a gap between two sizes, and then the larger one is the right one. Where two sizes overlap, take the one that holds his number farther from its edge. Here neither case comes up.

Say the tape reads 46 cm. That is S. Say it reads 55 cm. That is M.

The chart puts French Bulldogs under S, and it puts Corgis and Bichons there too. A breed is a hint. The tape is the answer, and a stocky Frenchie can measure into M.

This harness is sized by tape, not by scale. A puppy who has not come home yet cannot be measured, so wait for the tape. If the number is under 42 cm, he is below S, and our Puppy Harness starts at 32 cm.

The neck strap has a floor of 40 cm, so measure the neck as well

Chest gets all the attention. The neck is where this harness can go wrong.

The neck strap in S shortens to 40 cm. In M it shortens to 45 cm. It cannot go tighter than that.

Wrap the tape around the base of his neck, where the strap will lie, and keep it flat and snug, the way you did on the chest. Read the number as it is and look it up in the neck column, because nothing gets added here either.

Say his neck tapes 42 cm: that sits inside the 40 to 48 cm of size S, 2 cm above the floor. Say it tapes 37 cm and it is 3 cm under the floor.

If it lands under 40 cm, the strap cannot take out all the slack. Slack is how a dog backs out. In that case this is not your harness.

Take the Saddle Harness instead. Its size S has a neck strap that starts at 32 cm, and its chest range runs from 34 to 63 cm.

Ten minutes at the front door before the first walk

Close both buckles. Pull the neck strap until two flat fingers fit under it, then do the belly strap the same way. Three fingers means loose. One finger means tight.

Look at the panel. It should lie across his shoulders, with the handle between his shoulder blades. Clip the leash to the D-ring and lean back on it, gently. If the panel slides toward his neck, tighten and test again.

Now test the metal. Take the D-ring in one hand and the handle in the other and give each a firm pull. A buyer of a different leopard harness wrote: “Ripped first walk ring broke off my dog was loose.” Do that pull indoors, not at the curb.

Straps loosen a little with use, so run the same test again on the tenth walk.

Where the belly strap lies decides whether he gets a sore patch

“Harness creates chafing no matter what.” That is a thread title on a dog-training forum, and plenty of owners would sign it.

Lift one front leg and look at the hollow where the leg meets his body. You want to see fur there, not strap. The belly strap belongs behind the hollow, on his ribs.

A harness that is too big shifts, and a harness that shifts rubs. If a strap keeps sliding into the hollow, check the size chart before you tighten it again.

Do the check after a walk, when he is warm and the straps have settled. Here is when to look.

If the skin looks red, stop using the harness and ask your vet.

If he freezes when it touches his neck, give him three days

Some Frenchies stand still for anything. Others go stiff the moment a strap comes near their neck. This part is for the second kind.

On day one, leave the harness on the floor beside his dinner bowl and let him sniff it. On day two, lay the panel across his back with both buckles open. Give him a treat and take it off.

On day three, close the belly strap only. Walk to the door and back, then take it off. Add the neck strap once he ignores the belly strap.

Do not turn it into a fight. If he still sits down and will not move after three days, this may not be his harness. Send it back within the shop’s 30 days. Our Plain Mesh Step-In goes on by stepping in and closes behind his shoulders, so nothing goes near his head.

One ring on his back turns nothing, so a leaner should look at two other harnesses

The D-ring sits on his back, beside the handle. There is no ring on the chest.

Here is what that means on a walk. When he lunges, the pull goes straight forward and nothing turns his front end toward you. On a slack leash that does not matter. If he leans into the leash at every corner, the Front-Clip Harness has a ring low on the chest panel.

The handle is for steadying him at a curb or a door. Do not carry him by it.

Two other harnesses in the shop answer questions this one does not. Here they are in one table.

Pick this one for the leopard panel and a harness that opens flat. Pick the Saddle Harness if a leash in the box matters, or if his neck is under 40 cm. Pick the Front-Clip Harness if he leans. Both go over his head, so they are for a dog who lets you do that.

This harness is the wrong one for a dog whose chest number is over 62 cm or under 42 cm. It is the wrong one for a dog who pulls hard, because the ring is on his back. And it is the wrong one if you want a leash in the box, because there is none.
