The right harness for a French Bulldog matches the tape around his chest, just behind the front legs, and clips the leash where his walk needs it. A leash point on his chest turns a lunge back toward you; one on his back only carries the pull.
9 shelves, and each one answers a question about your dog. He lunges at corners: start with Front-Clip. He backs away from anything over his head: Step-In has two where his paws go in. The puppy is not home yet: on Small Dog & Puppy, the Puppy Harness starts at a 32 cm chest (12.6 in).

Why only harnesses
A collar puts the whole pull on the neck. A harness spreads it across the chest — if it is cut for a Frenchie and not for a Labrador in a smaller size.
Most harnesses are built for a deep, narrow chest, so on a Frenchie they ride up under the front legs or slip sideways. “The harness tends to pull and twist to the side a lot,” one owner wrote on Reddit.
Here’s what that means when you order. Put a tape around his chest, just behind the front legs, and find that number in the size chart on the product page. Where a chart also lists a neck figure, check that too.
If his number falls in the gap between two sizes, take the larger; if two sizes both cover it, take the one where it sits farther from the edge of its range. Two flat fingers should slide under every strap, and it is worth checking again on his first, third and tenth walk.
No harness here teaches loose-leash walking, and none of the four car belts is crash tested. A leash point on his chest turns a lunge. Teaching him to walk beside you is still your job.
See the harnessesA 25 lb (11.3 kg) Frenchie takes the Front-Clip in M, and its S starts at 4 kg (8.8 lb). The four car belts join a harness to your seat belt; they are not harnesses themselves.


























The one sized to his chest that clips the leash where his walk needs it. Front-Clip, Quick-Dry Reflective, Reflective, Saddle and Tactical have a leash point on the chest, for a dog who lunges. Most of the rest clip on his back, which suits a calm walker.
One with a leash point on his chest, because a lunge then swings his front end toward you instead of running straight ahead. Front-Clip has foam under its chest ring. It turns a lunge; it does not teach loose-leash walking. No harness here does. That part is still yours.
The size that matches a tape around his chest, just behind the front legs. Find that number in the chart on the product page, and if he falls between two sizes, take the larger. A 25 lb (11.3 kg) Frenchie takes the Front-Clip in M.
For walking, a harness. A collar puts the whole pull on his neck, and on a thick Frenchie neck many collars slide off. A harness spreads the pull across his chest. A collar still has a job: it holds his ID tag.
One you size by chest, because a puppy changes shape every month. Our Puppy Harness comes in XS to L for chests from 32 to 49 cm (12.6 to 19.3 in). If he is not home yet, order by weight: XS starts at 3 kg (6.6 lb).
Yes, if your Frenchie backs away from anything over his head. He steps into two openings and one buckle closes on his back. The leash then clips on his back only, so it carries a pull and does not turn it. Bear Set and Y work this way; the Plain Mesh, despite its name, goes over his head.
Two fingers should slide flat under every strap. If they will not go in, take the next size up. Check again on his first, third and tenth walk. If he is between two sizes, take the larger one.
