Matching harnesses for two Beagles

Two Beagles wanting matching harnesses is a great idea — the tricky bit is that Beagles vary more in chest size than people expect, especially between a 2-year-old still filling out and a 5-year-old fully grown. Harness fit is everything here: a poorly fitted harness restricts movement, causes chafing at the armpits, or lets a determined Beagle back out of it entirely — and Beagles are very determined. The right type depends on what you're using them for too. Can you tell me roughly how much each dog weighs, whether you're walking them together or separately, and whether either one pulls?

That's a useful difference — 10kg and 13kg puts them in adjacent size brackets rather than the same one, so you'll need different sizes even within the same harness range. Because the younger one pulls, I'd lean toward a front-clip or dual-clip option rather than a standard back-clip, which does nothing to discourage pulling and can actually encourage it. Does the younger one lunge suddenly, or is it more steady forward pressure? And are you happy adjusting two separate harnesses each walk, or do you want something quick to put on?

Completely understandable. For steady pulling with a quick-fit priority, the Julius-K9 IDC Powerharness is what I'd go to. It comes in a size 0 (roughly 9–11kg chest) for your younger one and a size 1 (12–15kg chest) for the older one — same design, different sizes, so they'll look matching. The chest strap fastens with a single clip over the back, which is genuinely fast once fitted. It has both a back D-ring and a front attachment point, so you can use the front clip on the younger one to take the edge off that pulling without buying a completely different style. The build quality is solid — padded chest plate, reflective trim, and the fit is very adjustable within each size range, which matters for Beagles because their deep chest and narrower waist can catch cheaper harnesses out.

The Julius-K9 size guide is reliable but you do need to measure chest girth — not weight — to be sure. Wrap a tape around the widest part of the chest, just behind the front legs. For Beagles, the chest is often wider than the weight would suggest, so a 10kg dog can sit firmly mid-range in size 0 while an 11kg one might be close to needing size 1. If either dog measures within about 2cm of the top of a size range, go up. It's much easier to tighten than to return. Both sizes are usually available individually on Amazon UK, so you don't have to buy a pack.

Good plan. Once you have them, clip the front ring on the younger one first for a few walks and you should notice the pulling reduce fairly quickly — it changes the direction of pressure without any correction needed from you. If the older one ever needs the front clip too, it's there. Enjoy walking them together.
