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

Hot spots under the armpits are a real problem with harnesses — most designs trap heat and moisture right in that zone, which makes existing irritation significantly worse. Before I point you toward something specific: how heavy is your Staffy, and whereabouts do the hot spots sit — is it the front armpit area, behind the front legs, or both? And is he currently on any treatment for them, or are they more of a recurring thing you're managing ongoing?
He's about 18kg, stocky build like most Staffies. The hot spots are in both armpits, front legs. They come and go — vet says it's partly friction and partly him running hot. He's on walks twice a day, nothing extreme, but he does pull a bit.

That combination — friction plus a dog that runs warm — really does narrow the options. Most padded harnesses are the enemy here because the padding holds heat and the edges rub exactly where his hot spots are. You need something with open mesh construction, minimal material contact under the arms, and ideally a design that doesn't have a wide chest strap sitting right across that problem area. The pulling also matters — a back-clip alone won't help much with an 18kg Staffy who pulls, so you want dual-clip capability. Can you tell me whether the hot spots are worse in summer, or is this a year-round issue?
Definitely worse in summer but honestly they never fully clear up. Winter is more manageable.

Right, so breathability has to be the primary spec, not just a nice-to-have. Here's my recommendation: the Ruffwear Front Range Harness. It's a dual-clip design — front ring for managing pulling, back ring for general walking — so it covers both your needs. The key thing for your dog is the construction: it uses an open-air mesh along the body panel rather than solid neoprene or dense padding, which means airflow rather than heat-trapping. The chest and belly straps are slim and positioned to keep material away from the armpit crease as much as any harness realistically can. For an 18kg Staffy you'd be looking at a Medium — Staffies are barrel-chested so measure his girth snugly behind the front legs before ordering, as some sit between sizes. It's not a magic fix for the hot spots, but it's the most sensible harness choice given what you're dealing with.
That sounds good. Is there anything I should do differently when putting it on to avoid making the rubbing worse?
inparticular.ai
Yes — a few things make a real difference. First, fit it so you can fit two fingers under every strap, but no more; a loose harness shifts around and causes more friction than a snug one. Second, check the armpit area after every walk, especially in warm weather — if you're seeing any redness developing, that's your cue to re-adjust before it becomes a hot spot. Some owners with sensitive dogs also put a thin layer of a barrier cream like Vaseline on the skin contact points before longer walks, though check with your vet if his skin is already broken. And rotate removal — don't leave it on between walks, give the skin time to breathe and dry out fully.
Really helpful, thank you. I'll measure him up and go for the Medium.

Good call on measuring first — it's worth the 30 seconds given his build. One last tip: when it first arrives, do a few short wear sessions at home before a full walk, so you can check exactly where it sits on him and make micro-adjustments while it's easy to fine-tune. Hope it makes a genuine difference to the hot spots.
