This is a specific conversation about Dog leashes — finding the right one — ask about yours and get one honest answer for your exact situation.

A 16-week-old French Bulldog starting leash training is exactly the situation where getting this right early really pays off. Leash choice matters more than most people think — length, material, and attachment type all shape how walking and training actually go. That said, your instinct about neck pressure is spot on for Frenchies specifically. Before I point you in the right direction, can you tell me roughly how much your pup weighs right now, and are you mainly thinking about short garden sessions to get them used to wearing something, or are you already heading out on pavements?
She's about 5kg at the moment. Mostly garden sessions right now but I want to start short pavement walks soon. I've read Frenchies can have breathing problems so I don't want anything round her neck at all.

Completely the right call. French Bulldogs are brachycephalic — that flat face means they're already working harder to breathe, and any collar pressure on the trachea can make that worse, especially when a pup is pulling or startled. At 5kg and 16 weeks, her neck and airway are still very small and delicate. A harness is absolutely the way to go, and for this age and breed I'd steer you away from front-clip harnesses too — at this stage you just want something comfortable and well-fitting that she can get used to wearing, not a tool that corrects direction. Has she worn anything on her body before, or is this completely new for her?
Nothing at all yet. She's quite wriggly when I pick her up so I'm a bit worried about fitting it.
inparticular.ai
That's really helpful to know. For a wriggly puppy who's never worn anything before, you want a harness that goes on easily — ideally step-in style rather than over-the-head, so there's no fumbling around her face, which can make pups anxious about the whole process. It also needs to be properly adjustable given how fast Frenchie puppies change shape in those early months. The one I'd point you to is the Ruffwear Front Range Harness. It has four adjustment points so it fits snugly without being restrictive, padding across the chest and belly so there's no rubbing, and a back-clip D-ring that keeps pressure completely off the neck. It's well made, tested for small dogs, and available in sizes that suit a 5kg pup. It's not the cheapest option but it'll last her well past puppyhood given how adjustable it is. Pair it with a standard 1.2m or 1.5m flat lead for now — nothing retractable at this stage, you want her close and responsive while she's learning.
That sounds perfect. Is there a specific size I should be looking at for her measurements?
inparticular.ai
Yes — measure the girth around the widest part of her ribcage before you order. At 5kg most Frenchie pups at 16 weeks sit in the XXS or XS range on the Ruffwear Front Range sizing chart, but girth is what actually determines fit, not weight. Ruffwear publish their size guide clearly on their site and on the Amazon listing. If she's right on the border between two sizes, go up — you can always tighten the straps, and you'll get more use out of it as she grows. The chest pad on the Front Range also means a slightly roomier fit is comfortable rather than sloppy.
Great, thank you. One more thing — should I use a collar at all, even just for her ID tag?
inparticular.ai
Yes, a flat collar for ID is fine and actually legally required in the UK when she's out in public — just make sure it's loose enough that you can slide two fingers under it easily, and never attach a lead to it. Keep the lead on the harness always. There are also ID tag attachments designed to clip directly onto harness D-rings if you'd rather skip the collar entirely at home, but most owners just use a lightweight flat collar purely for the tag. Either approach works — the key rule is simply: lead always goes on the harness, never the collar.
