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

Padded harnesses and wiry coats are a bad combination — the friction and bulk are almost guaranteed to cause matting, especially around the chest and shoulders where the padding sits tight. Switching to a minimalist webbing design is exactly the right call. Before I point you to a specific harness, a couple of quick questions: how much does your Border Terrier weigh, and is this mainly for daily walks or does he pull much on the lead?
He's about 7kg, so fairly typical for the breed. He does pull a bit when he spots something interesting — he's a terrier, so that's pretty much constant — but it's manageable. Mainly want something that won't wreck his coat again.

Got it — 7kg, moderate pulling, and coat protection is the priority. Have you noticed where the matting was worst with the old harness? Around the chest, under the armpits, or across the back? That'll help me confirm the right design.
Mostly under his armpits and along his chest. The padding seemed to bunch up there and just ground the fur down over time.

That's classic padded-harness damage on a wiry coat — the foam holds moisture and creates that constant rubbing action. What you want is thin, smooth webbing with no padding at all, ideally with a chest strap that sits high rather than across the lower chest where the fur is densest. For a 7kg Border Terrier, I'd go with the Ruffwear Flat Out Harness. It's a proper minimalist webbing design — no padding anywhere — with a single chest strap that's easy to position high on the sternum, well clear of the armpit fur. It has both a back clip and a front clip, so the front option will help take the edge off his terrier pulling without you needing a separate lead-training harness. The webbing is narrow and smooth, which means minimal contact with the coat. At his size you'd be looking at the XS. It's a bit more money than a basic webbing harness, but the build quality means it won't stretch out of shape and start rubbing in new places after a few months.
That sounds promising. Is the XS definitely right for a 7kg Border Terrier, or should I measure him first?

Always measure — don't go on weight alone with Ruffwear. Their XS fits a girth of roughly 43–56cm, so measure the widest part of his ribcage just behind his front legs. Border Terriers can run slightly barrel-chested for their weight, so a few of them land in the Small (51–69cm). If he's right on the border between sizes, go with the larger one — a slightly looser fit is far less damaging to a wiry coat than a snug one, and Ruffwear's buckles give you enough adjustment range to dial it in properly.
Really helpful, thank you. I'll measure him before ordering.

Perfect — that's the right approach. Once it arrives, check that you can fit two fingers flat under every strap, and make sure the chest strap sits visibly above the armpit crease when he's standing still. If it slips down during the first walk, just readjust before you head out again; webbing harnesses settle slightly once the dog has moved in them. He should stay mat-free with this one.
