This harness goes over his head, then two buckles click shut under his ribs

One owner named what mattered most in a harness: “doesn’t go over the head (which my guy hates).” If that is your dog, here is the answer before anything else. This harness goes over the head.

The neck loop is one closed ring of strap, with a slider on each shoulder and no buckle. Only the belly strap opens. It has a plastic side-release buckle on each side.

Here’s the order that works.

First, open both buckles and slide every strap out to its longest, before your dog is in the room. Second, hold the neck loop open with both hands and lower it over his head, past his ears, in one slow move.

Third, check the panels. The small one with the handle and the ring lies between his shoulder blades. The wide one with the low ring lies on his chest.

Fourth, reach under him and click each buckle into its housing on the back panel. Fifth, tighten the neck sliders, then the belly sliders, until two flat fingers slide under each strap.

If he ducks when your hands come near his ears, choose another design. Our step-in harness closes behind the shoulders and never touches his head.

Two panels, four sliders and two rings: every part is in this table

Laid flat, this harness is two pieces joined by the neck straps. The small piece is the back panel. The big piece is the chest panel, and the belly strap runs out from its base.

Here is each part, where it sits and what it is.

The whole harness weighs 148 g (5.2 oz) in S and 163 g (5.7 oz) in M. The outside is polyester. The underside of both panels is black mesh, and that is the side that touches his coat.

Two rings, two jobs: the chest ring turns him, the back ring only holds the leash

“The harness tends to pull and twist to the side a lot… it’s adjusted as best as possible.” An owner wrote that, and it names two different problems. One is a dog who leans. The other is a harness that will not stay straight.

Take the lean first. Clip the leash to the back ring and his lunge goes straight ahead, so nothing turns him. Clip it to the chest ring and the same lunge swings his front end toward you.

A front ring turns him. It does not teach him to stop pulling. What teaches him is you standing still until the leash goes slack, and a treat when it does.

The twist is nearly always slack. With three fingers of room under the belly strap, the harness swings to one side every time he veers. Take up the belly sliders until two fingers fit. Then look down at the chest panel: it should sit in the middle of his chest.

Say your Frenchie is calm on your own street and pulls near the park. Clip the back ring on your street. At the park gate, move the clip to the chest ring. Same leash, same harness, a different ring for a different walk.

Our front-clip harness has the same two-ring layout, and its page goes further into how the chest ring works.

A 25 lb Frenchie takes S or M, and the chest tape decides which

“Sizing recommendations for a typical 25 lb frenchie?” An owner asked that, and weight alone cannot answer it.

The chest tape picks the size, and weight only checks it. The weight ranges are 4 to 7.5 kg (8.8 to 16.5 lb) for S and 7.5 to 17.5 kg (16.5 to 38.6 lb) for M. A 25 lb Frenchie weighs 11.3 kg, which is in the range of M. If his chest tapes 48 cm, the tape says S, and the tape wins.

The breed standard stops at 28 lb (12.7 kg), which is inside the weight range of M. The two chest ranges overlap from 38 to 63 cm. Those numbers show how far the straps travel, not how big a dog is, so the tape has to settle it.

A dog near 7.5 kg sits on the line between the two weight ranges, so weight cannot settle him either. The tape points to S from 34 to 50.4 cm and to M from 50.5 to 75 cm. From 38 to 63 cm both sizes hold him, so take the one that leaves his number farther from the end of its range.

At exactly 50.5 cm the two are level, and a tie goes to M, because a harness can be taken in but not let out. A gap between two sizes would be different, since there the larger one is right. Here the ranges run without a gap from 34 to 75 cm.

Here are two more dogs. A 6 kg (13.2 lb) puppy who tapes 40 cm takes S, and his weight agrees. A 12.7 kg (28 lb) adult who tapes 55 cm takes M, and his weight agrees again. A chest over 75 cm (29.5 in) is outside M, and under 34 cm (13.4 in) he is below S.

Tape him behind his front legs, flat and snug, and find that number in the chest column

The tape does one job the scale cannot. It catches the dog who is heavy but narrow, or light but broad.

Stand him on a floor he does not slip on and use a soft tape. Go around his body just behind the front legs, at the widest part of his chest. Keep the tape flat, with no slack and no squeeze, and write down exactly what it reads. That number goes into the chest column as it is, with nothing added.

Say the tape reads 45 cm. Both sizes close on that, but 45 sits 11 cm inside S and only 7 cm inside M, so it is S. At 56 cm it is the other way round, with 7 cm inside S and 18 inside M, so it is M.

The same rule holds at the edges. At 38 cm M has only just started, so it is S, and at 63 cm S has just ended, so it is M.

Next, the neck. Measure around the base, where the loop will sit, the same flat and snug way. Read both numbers against the table above.

Two fingers come later, when the harness is on him and buckled, and then two flat fingers should slide under each strap. That checks the fit and is not part of the measuring.

“I’m getting my first bulldog a week from now and making all my purchases now.” If that is you, there is nothing to measure yet.

Ask the breeder for his chest measurement on pick-up day, and for his weight beside it. Under 34 cm (13.4 in) he is below S, and our puppy harness starts smaller. From 34 cm up he takes S, until the tape reads 50.5 cm (19.9 in) or more.

The strap that rubs is the one that slid behind his front leg

“Always causes chafing/redness under my pup’s armpits.” An owner wrote that, and the cause is usually one strap in one place.

The belly strap belongs across his ribs, behind the front leg. It should not sit in the hollow where the leg meets his body. A loose strap slides forward into that hollow with every step. If the strap is already at its longest and still creeps forward, the harness is too small. Take the next size up.

Here is a check that takes a minute, and when to do it.

Flattened or rubbed fur is your cue to move the strap and look again the next day. If the skin looks red or sore, stop using the harness and ask your vet.

If he freezes in it, take it off and start again on the kitchen floor

“She was just stubbornly sitting and wouldn’t move.” A new harness does that to some dogs. The fix is not a longer walk. It is a shorter first day.

Start indoors, before dinner. Lay the harness on the floor and let him sniff it. Lower the neck loop over his head, close the buckles, count to ten, give a treat and take it off. That is day one.

On day two, leave it on for as long as his meal lasts. On day three, walk him up and down the hallway on the leash. Go out the front door only when he trots in it as if it were not there.

If he sits down and refuses, take it off, praise him anyway and go back one step. Days, not minutes, is the normal pace.

The handle holds him at a curb, and it does not lift him

The handle is a black webbing loop across the top of the back panel, right above the back ring. Use it where the leash is too long: at a curb with a bus coming, in a doorway, at the car door. Close your fist on it and he stays beside you.

It is for holding him, not for lifting him. When you carry your Frenchie, put both hands under his chest.

Silver thread in every strap, six colors, and a black rope leash in the box

The webbing carries a line of silver dotted thread, the reflective kind. It has no battery and does not glow by itself. On a November evening at five, a car turning into your street sends its headlights onto that thread and back to the driver. In daylight you just see the dots.

Green, blue, orange, red and purple each have a stripe in the panel color down the middle of every strap. The black harness is black all over, with silver dots.

The leash is a round rope with a padded loop at one end and a snap clip at the other. It is black in every color. Size S comes with a 1.2 m (3.9 ft) leash, and size M with a 1.5 m (4.9 ft) one.

Four kinds of Frenchie should skip this harness, and we would rather say so

If he hates anything going over his head, take a step-in harness.

If his chest tapes under 34 cm (13.4 in), he is below S. Take the puppy harness.

If his chest tapes over 75 cm (29.5 in), he is outside M.

If you want rows for patches and a pouch, take the molle vest. This harness has none.

No harness is a promise that a dog cannot back out of it. A loose one can slip off. Two flat fingers of room under every strap is the limit.

Next to our front-clip harness this one has the same layout, and only the step-in skips the head

Here are the three harnesses a Frenchie owner is most likely to weigh against each other.

The front-clip harness and this one are built the same way, so the choice between them is about colors, the leash in the box and how each size is picked. The step-in is the one to pick if the head is the problem.
