This is a specific conversation about Dog pulling on the lead — what actually works — ask about yours and get one honest answer for your exact situation.

A harness cutting into a Doberman's armpits after two months is a real problem — at that age they can put on centimetres in chest and shoulder width almost weekly, and a harness that digs in will cause soreness and make them resist walking altogether. The most effective tools for lead pulling are no-pull harnesses and head collars, but fit is everything and off-the-shelf sizing often can't keep up with a fast-growing large breed. To point you to the right thing: how much does your Doberman currently weigh, and is the pulling constant or mainly when something exciting appears ahead?
He's about 28kg now but the vet says he's going to be a big one, probably 40kg+ by the time he's fully grown. The pulling is pretty relentless — he's strong and he just wants to be everywhere at once. Classic young Dobie really.

That's exactly the Dobie problem — huge enthusiasm, already significant strength, and still months of growth ahead. A standard harness bought even recently is going to be the wrong size within weeks. Before I give you a recommendation, one question: where does he pull from most — chest forward like a freight train, or does he lunge sideways and spin as well?
Pure freight train. Dead ahead, nose forward, just goes. No spinning, just relentless forward pressure.

Perfect — that tells me exactly what you need. I'd go straight to the Perfect Fit modular harness. It's made in the UK and built from three separate sections — top, front, and girth — that you buy to fit your dog's actual measurements right now, and you replace individual sections as he grows rather than buying a whole new harness each time. For a Doberman with straight-ahead pulling it works brilliantly: the front-connecting D-ring gives you steering control without yanking, and because nothing is pulling tight across the armpits the fit stays comfortable even as he fills out. You measure chest girth, neck, and back length, then choose each section size independently, which is genuinely the only sane approach for a dog that's going to add 12kg before he's done. It's stocked on Amazon UK and directly through the Perfect Fit website. Size guide on their site is thorough — use it, don't guess.
That sounds really sensible actually. Is it strong enough for a dog his size though? He can genuinely pull me off balance.

Yes — the webbing and stitching are rated well above what a Doberman can generate, and the modular clips are solid. The harness itself won't fail. What I'd add is this: for a dog that can pull you over, pair it with some loose-lead work from day one with the new harness. The front attachment redirects him when he surges, but if he's never had any training on it he'll still try. Even ten minutes a day of stop-start walking where forward movement only happens on a loose lead will make a dramatic difference within two to three weeks at his age. He's young enough that he'll pick it up fast.
Really helpful, thank you. I'll measure him up today and order it.

Good plan — measure twice, the guide is clear and it's worth the effort. One practical tip: when it arrives, put it on him indoors for short sessions before you head out so he gets used to the fit and the front ring without the excitement of a walk layered on top. At seven months he'll adapt quickly. You should notice the difference in the first few outings.
