This is a specific conversation about No-pull harnesses — what actually works — ask about yours and get one honest answer for your exact situation.

Cycling with a dog daily is a brilliant setup, but it puts real demands on the harness — it needs to handle forward momentum without letting the dog lurch sideways into your wheel, and it must have a secure back-clip point that pairs properly with a bike attachment like a Springer or Walky Dog. Not all no-pull harnesses are equal here: front-clip designs are great for on-foot walking but can interfere with a bike lead, while dual-clip harnesses give you both options and tend to hold position better at speed. Fit is absolutely critical — a loose harness on a bike run is a safety hazard. So: what's your Dalmatian's rough weight and chest measurement, how hard does he pull when you're on foot versus running alongside the bike, and are you already using a specific bike attachment?
He's about 27kg, I haven't measured his chest but he's a fairly typical male Dal build. On foot he pulls pretty hard — definitely needs managing. On the bike he's actually better behaved, probably because he's working. I use a Walky Dog Plus attachment, which clips to the back of the harness.

That's a useful distinction — a dog who settles on the bike but pulls on foot needs a harness that handles both modes well. For the Walky Dog Plus you want a back clip that sits in a stable, central position on the body so the lateral arm can absorb side-pulls without twisting the harness. A 27kg Dalmatian is going to be a Large in most brands. What harness or collar are you currently using, and has anything rubbed or shifted position during longer rides?
Currently using a basic Julius-K9 harness — it clips at the back but the chest strap has started to rub under his front legs on longer rides. It also slips backward a bit when he surges forward on foot.

The Julius-K9 is a solid workhorse but that rub under the armpits and the slipping backward are classic signs the fit isn't quite right for his build — Dalmatians are quite deep-chested and narrow-waisted, which means many standard harnesses sit too far back. The backward slip is also why he can get leverage to pull on foot. Here's what I'd recommend: the Ruffwear Front Range Harness in Large. It has two clip points — a front chest ring for on-foot leash walking to reduce pulling, and a rear back clip that sits centrally and securely for the Walky Dog Plus. The padded chest and belly panels are cut to avoid the armpit zone that's been causing the rub, and the four-point adjustment means you can dial in the fit for a narrow Dal waist properly. It's well-tested for active use and holds position during sustained forward movement, which is exactly what you need at bike pace. For on-foot walks, clip to the front ring and the pulling becomes much more manageable without needing a separate head collar.
That sounds good. Is the back clip actually rated for the kind of force a Walky Dog generates, or is it just a standard D-ring?

It's a reinforced aluminium V-ring rather than a thin pressed D-ring, and the webbing around it is bar-tacked — it's built for trail running and active sport use, so it handles lateral and forward load well. Ruffwear design for working conditions rather than just walking, which is why it holds up better than most lifestyle harnesses under sustained pull. The Walky Dog Plus attachment distributes force through your bike frame rather than into one hard jerk point, so in normal use the harness isn't taking shock loads — but the construction is solid enough that it would handle it if he did lunge. Just make sure you size to his actual chest girth when it arrives; Large covers roughly 69–81cm chest, which should suit a typical male Dal, but Ruffwear's sizing guide is reliable if you measure him.
Perfect, that's exactly what I needed. I'll measure him and order the Large. Thanks.

Good plan — measure the widest part of his chest just behind the front legs and you'll be confident in the size. If he's right on the boundary between Medium and Large, go Large for comfort on long rides. Enjoy the daily rides with him — Dalmatians are made for that kind of exercise.
