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

A one-year-old rescue mongrel is a bit of an unknown quantity — still maturing, size possibly still shifting, and often pulling hard because the world is exciting and new. Not all no-pull harnesses are equal: front-clip designs work well for most dogs, but strong pullers often need a dual-clip harness or even a head collar, and fit is everything — a loose harness just rotates and does nothing. What size is your dog roughly now, how hard are they pulling, and have you tried any no-pull gear before?
She's about 18kg right now but the vet thinks she might still grow a bit — maybe up to 22 or 23kg. She pulls really hard, proper lunge-and-drag stuff. I haven't tried anything yet, just a normal flat collar. I'm on a low income so I need something that won't fall apart quickly but I can't spend a fortune.

That lunge-and-drag pulling means you definitely need a front-clip harness at minimum — clipping at the chest redirects her sideways when she pulls, which breaks the momentum without hurting her. Given she might grow another few kilos, you also want something adjustable enough to last. What's her chest girth roughly, if you know it? A rough measure around the widest part of her ribcage will tell us which size you'd need.
I just measured — it's about 62cm around her chest. I don't really have a tape measure so I used a piece of string and measured that, hope that's close enough!

That's perfect, string works fine. At 62cm chest you're in a comfortable medium range for most harnesses, and with room to grow to 22–23kg you've got good options. For your situation — strong puller, possible growth, needs to last on a budget — I'd go with the Julius-K9 IDC Powerharness in size 1. It's a genuine workhorse harness: thick webbing, sturdy chest buckle, front and back attachment points, and it's been around for decades for a reason. It fits chest 58–76cm, so she has room to grow into it. It's around £30–35 on Amazon UK, which is mid-range but it won't shred or warp after six months of hard use the way cheaper harnesses do. The front clip will make a real difference to the lunging almost immediately.
That sounds good. Will it actually last though? I've had cheap harnesses on previous dogs that just snapped or the buckle broke after a few months.

The Julius-K9 is genuinely built for working dogs — it's used by police and search-and-rescue handlers, so consumer daily use is not going to stress it. The buckles are chunky and rated for real load, the stitching is reinforced, and the velcro ID panel on the side (which you can ignore if you want) doesn't affect structure. The one thing to check when it arrives is that the chest strap sits across the breastbone, not up near the throat — that's the fit mistake that makes harnesses spin. If you take five minutes to adjust it properly on day one, it should last her years, even if she grows a bit more.
Great, that's really helpful. I'll order it. Is there anything I should do alongside the harness to actually reduce the pulling, or will the harness do it on its own?
inparticular.ai
The harness reduces the power of the pull — it doesn't teach her not to pull. The most effective thing alongside it is stop-start walking: the moment she hits the end of the lead, you stop completely, wait until she looks back or the lead goes slack, then walk on. No yanking, no shouting — just stop. It feels slow at first but most dogs click onto it within a couple of weeks. She's only one, so her brain is still very trainable. Harness plus consistent stop-start will get you somewhere genuinely useful.
