He hates it over his head, so this harness closes on his back instead

“Doesn’t go over the head (which my guy hates).” A Frenchie owner wrote that on r/Frenchbulldogs, and it is the whole brief for this harness.

Here is how it goes on. Two wide fabric bands cross on his chest and make an X. One buckle closes on his back. You lay the X against his chest, bring the straps up over his shoulders, and click the buckle shut behind them.

Nothing passes over his ears. Nobody lifts a paw through a hole. If he ducks away from a loop near his face, he will not meet one here.

Four sliders sit at the four corners of the X. They set the length of each strap, so you can shift the crossing until it lies on his breastbone.

It weighs about 60 grams, and this is everything those 60 grams are made of

A large egg weighs about 57 grams. This harness is close to that. The bands are twill, a fabric with a fine diagonal rib, and the inside is lined with air mesh. You can see the mesh along the cut-out edges.

The table lists every part, from the chest to the leash.

That is the whole list. There is no ring on the chest and no handle to lift him by. If either one matters to you, the last sections say which of our harnesses has it.

Tape him snug behind the front legs, then read the row that holds that number

Use a soft tape, like the one in a sewing box. Wrap it around his ribs right behind the front legs, at the widest point. Keep it flat and snug. Write the number down.

That number goes straight to the table, and nothing is added to it first. Each size covers a range of chests, and the four sliders adjust the fit inside it.

Two fingers come later, on the dog: once the harness is buckled, two flat fingers should slide under every strap. Here is the chest each size is cut for.

A tape of 48 cm is an L, because it sits in the middle of that row, nowhere near an edge.

The rows overlap in two places, at 42–43 cm and at 53–55 cm. A tape there is held by two sizes. Take the one where the number sits farther from the edge of its row.

A tape of 42 cm is 1 cm inside the M row and right on the edge of the L row, so it is an M. A tape of 54 cm is 1 cm inside both the L and the XL, exactly in the middle of the overlap, so take the larger and call it an XL.

If a number falls in a gap between two rows, the larger size is the right one. This table has no gap between 35 and 65 cm, so only the overlap rule will come up.

Is the puppy not home yet? If the breeder has only a weight, wait and tape him on day one. A weight says roughly where to look: a 25 lb Frenchie weighs 11.3 kg, which is the L column. It does not choose the size.

Weight only checks the size. A Frenchie carries a lot of his weight in his chest, so two dogs of the same weight can want different rows. Tape him on day one and let the tape win.

Under 35 cm on the tape, the M is too big, and a dog under 4 kg is below it on the weight check too. Our puppy harness closes down to a 32 cm chest. Over 65 cm on the tape, the XL is too small. Our denim harness set closes on a chest up to 66 cm.

Where the straps lie decides whether he rubs, so check four spots before the first walk

“Harness creates chafing no matter what.” That is the title of a thread on r/Dogtraining. No harness can promise that a dog will never rub. What you can do is see where every strap lies. Then you catch a problem on the first walk, not on the thirtieth.

Do it indoors, with a treat in your hand and the harness on him. Look at four spots.

First, the crossing. It should lie on his breastbone, in the middle of his chest. If it has slid to one side, compare the sliders on the left and the right. They should sit at the same length.

Second, two fingers. Two flat fingers should slide under every strap. If you cannot get two in, loosen it.

Third, the belly straps. They belong on his ribs, behind the front legs. A strap that has crept up into the hollow behind his elbow is the first one to move.

Fourth, the buckle. It sits on his back, in the middle, not slid off to one side of his neck.

After the first walk, take the harness off. Look at the fur under every strap and behind each elbow. Pink skin or a bare patch means stop, and ask your vet. Look again after the third walk and the tenth. Straps settle, and a growing puppy needs the tape again.

If the X drifts to one side on the walk, look at the four sliders before anything else

“The harness tends to pull and twist to the side a lot.” An owner wrote that on r/Frenchbulldogs. The harness had been adjusted to fit the dog as well as it could be. An X has four sliders, and any one of them can end up a little off.

Take it off and lay it flat. Look at the four sliders. The two at the top of the X should sit at the same length, and so should the two at the bottom. Put it back on and check the crossing again.

Then check for slack. Two flat fingers under a strap is the limit. A strap with more room than that lets the whole X slide when he turns.

Change one slider at a time, and walk a few steps in the hall after each one. It is slower than tightening everything at once. It also shows you which slider was the problem.

If he sits down and refuses to walk, keep the harness indoors for a few days first

“She was just stubbornly sitting and wouldn’t move.” An owner wrote that about a dog in a harness. It happens. A new thing on his body and a new street at the same time is a lot.

So split the two. Put the harness on in the kitchen, give him a treat, and take it off after a few minutes. Do that a few times a day. When he stops noticing it, walk him around the living room on the leash. Then go outside.

There is no loop to slide over his ears, so the first step is only the buckle. It clicks behind his shoulders, where he cannot see it.

If he freezes on the sidewalk, wait or carry him home. Try again tomorrow.

The 1.5 m leash is rope with a foam handle, and it clips to the rings on his back

The leash is in the box, in the color of the harness. It is 1.5 m long, which is 4.9 ft. It is a round braided rope, not a flat strap. A black foam loop forms the handle, and a gray sleeve covers the join where the rope meets the loop.

The foam is there so the loop does not dig into your hand when he lunges after a squirrel. At the other end, a gray sleeve sits above a metal snap hook.

The hook clips to the pair of rings at the top of his back. That is the only place the leash can go.

There is no ring on the chest, so a dog who leans into the leash needs a different harness

A bicycle whirs past, and your Frenchie throws himself forward. The leash ring is on his back. The pull goes straight ahead along his spine, and nothing turns his chest toward you.

A ring on the chest does turn him. It does not teach him to stop pulling. But if he leans hard every day, take our front-clip harness. It has a ring on the chest and one on the back. It goes over his head, so it is not for a dog who refuses that.

Here are the two harnesses closest to this one, side by side.

Our vest harness also never goes over his head. It lies across his back, and this one lies across his chest. If one sits badly on him, try the other.

The sizes decide it in one case. The vest is cut for 34–44 cm in M and 44–54 cm in L, with nothing added to the tape number. Above 54 cm, this X harness is the one that reaches, up to 65.

If you want a handle on his back, our grip-handle harness has one. It goes over his head.

Four pale colors, and the rope matches every one

The colors are cloud blue, mint, pale pink and egg-yolk yellow. Each harness comes with a rope leash in its own color. A raised round badge sits where the bands cross, with small black lettering on it.

Look at the photo of the fawn Frenchie on the city sidewalk. The crossing lies on his breastbone, and the leash clips to the rings above his shoulders.

When the box arrives, check three things before he wears it. The buckle should click all the way. Every slider should move when you push it, and hold when you let go. The rope should be firm where it joins the foam handle. Do it at the table, not at the front door.
