Made for French Bulldogs
Pick a French Bulldog puppy harness by chest, not age: tape him behind his front legs and match that number to the size table. “She was just stubbornly sitting and wouldn’t move,” one owner wrote about her 4-month-old on the first walks. Here is how to choose among our four.
None of the four has a ring on his chest, so none turns a puppy who lunges. Our Front-Clip harness does, and its S starts at 4 kg (8.8 lb). A 25 lb (11.3 kg) Frenchie is past the Mesh, which is rated to 10 kg (22 lb). The X Set in L covers him if his tape agrees. No harness teaches loose-leash walking.

The one whose size range holds his chest today. Up to a 49 cm (19.3 in) chest, that is the Puppy Harness: four sizes, 73 to 90 g, and a 1.5 m leash in the box. Wider than that, take the X Set, which closes at 65 cm (25.6 in).
Yes, once his chest reaches the smallest size. The Puppy Harness XS adjusts down to 32 cm (12.6 in), so his chest has to reach 32. Under that, it hangs loose.
Small. The American breed standard caps a French Bulldog at 28 lb (12.7 kg). He is broad in the chest, though, so size a harness by chest tape, not by the small-dog label.
For a 25 lb (11.3 kg) Frenchie, take the X Set in L if the tape lands between 43 and 53 cm. The Mesh is rated only to 10 kg (22 lb), and the Puppy Harness is cut for puppies.
Tape the widest part of his chest, just behind the front legs, flat and snug, and find that number in the size table. Nothing gets added to it. Two fingers are what you check once the harness is on him. 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, and the larger if it sits exactly on the line.
Two flat fingers should slide under every strap, and the chest strap belongs behind his front legs. If no finger fits, go up a size. Tape a growing puppy again every two weeks.
Yes, if he ducks from anything near his ears. The Puppy Harness takes his front legs through two openings and closes with one buckle on his back. The Knitted Vest and the X Set also go on without passing over his head. All three clip the leash on his back.
They can, when a strap sits in the hollow behind the front leg. On the Puppy Harness, the edge of each leg opening belongs on his chest. If the skin looks red after a walk, take it off and ask your vet.
