This is a specific conversation about Harnesses for small dogs — ask about yours and get one honest answer for your exact situation.

A nylon allergy really does change the harness hunt completely — most small dog harnesses are made almost entirely of nylon webbing, so you're ruled out of probably 80% of what's on the market before you even start. The right material matters as much as the fit here. To point you toward something that'll actually work: what does your Lhasa Apso weigh, and have you noticed whether the reaction is contact-only on bare skin, or does it come through their coat too? And is this mainly for daily walks, or do you need something they'll wear for longer stretches?
She's 5 years old and weighs about 6.5kg. The vet said it's a contact allergy — she gets red and itchy wherever the webbing sits against her skin, especially under her belly and behind her front legs. It's definitely worse where her coat is thinner. We mainly use it for walks, maybe 45 minutes a day.

That's really helpful. The belly strap and the girth area behind the front legs are exactly the pressure points that cause problems — those are where nylon webbing sits closest to skin, especially on a Lhasa whose coat can part under tension. Has she ever worn a soft-mesh harness, or has everything you've tried been standard webbing construction?
We tried one fleece-lined harness but it was still nylon underneath and she still reacted. We haven't tried anything that's fully non-nylon.

Right, that makes sense — a fleece lining helps with chafing but if the core webbing is still nylon and there's any skin exposure at the edges, you'll still get a reaction. What you need is a harness where the contact layer itself is a different material entirely. My recommendation for your Lhasa is the Tre Ponti Adjustable Harness — it's made in Italy and uses soft cotton-blend webbing rather than synthetic nylon throughout. The contact surface is genuinely different, not just lined. It's also an over-the-head step-in style with wide, flat straps that distribute pressure well across a small build like a Lhasa's, which means less concentrated friction at those exact points where she's reacting. At 6.5kg she'd be in their small size. It's well-made, washable, and I've not come across another small dog harness at this end of the market that avoids nylon this thoroughly.
That sounds promising. Is it easy to get the fit right? Lhasas have quite a deep chest and a short neck, and I've had harnesses that ended up sitting on her throat or slipping back toward her hips.

The Tre Ponti is one of the better ones for this exact issue — it has four adjustment points including an independent chest strap, so you can widen the chest opening without the whole harness shifting back. The girth strap adjusts separately from the neck loop, which is what lets you accommodate a deep chest and shorter neck together rather than compromising on one to fit the other. Measure her chest girth (the widest point just behind her front legs) and her neck circumference before you order, and check against their size chart rather than going by weight alone — at 6.5kg she might be right on the border of their sizing. You'll find it on Amazon UK.
Perfect, that's exactly the kind of detail I needed. I'll measure her up and go from there. Thank you.

Good luck — and if the first fit feels slightly off after a walk or two, the four-point adjustment means you can usually dial it in without starting over. Hope it gives her some relief from the irritation.
