An eight‑week‑old Frenchie is learning that something sits on his back at all. A heavy harness makes that lesson harder than it needs to be. This one is two layers of air mesh and a strip of reflective tape, and the whole thing weighs between 75 and 90 grams depending on the size.
| This puppy harness | Adult harness in a small size | Puppy collar | |

| Weight on the dog | 75–90 g | Usually 150 g and up | Light |
| Where the pull lands | Across the chest | Across the chest | On the neck |
| Leash included | Yes, 150 cm | Rarely | No |
| Widest chest | 49 cm | 60 cm and up | — |
Four sizes cover a chest from 32 to 49 centimetres, which is roughly eight weeks to eight months. After that he is wider than this harness closes and he moves to an adult one. Buying a grown‑up harness at twelve weeks does not work: the smallest adult sizes start where this one ends, and a harness that is too big slides sideways.
Every size ships with a 150 centimetre leash in the matching colour, with a reflective strip along it and a lightweight clip. Short enough to keep a puppy close on a pavement, long enough that he can sniff without dragging you.
Front legs go through the two openings and a single side buckle closes it on the back. Nothing passes over his face, which matters with a puppy who has decided that harnesses are a game.
Two Frenchie puppies of the same age can be four centimetres apart around the ribs.
| Size | Chest | Neck | Roughly |
|---|---|---|---|
| XS | 32–37 cm | 27–31 cm | 8–10 weeks |
| S | 34–42 cm | 28–34 cm | 3–4 months |
| M | 40–46 cm | 31–36 cm | 5–6 months |
| L | 42–49 cm | 33–39 cm | 6–8 months |
Measure just behind the front legs and leave two fingers of room.

Puppies change shape monthly, so measure before each size and not once. Chest is the number that matters; the weeks are only a rough guide.
| Size | Chest | Neck | Roughly |

| XS | 32–37 cm | 27–31 cm | 8–10 weeks |
| S | 34–42 cm | 28–34 cm | 3–4 months |
| M | 40–46 cm | 31–36 cm | 5–6 months |
| L | 42–49 cm | 33–39 cm | 6–8 months |
Hand‑measured at the factory, so allow a centimetre or two. When he is between two sizes take the larger one — he will be in it within a month anyway.
