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 Cane Corso who can physically overpower their owner is a genuine safety issue, not just an inconvenience — so I'm glad you're looking at this properly. For a dog that strong, the most effective tools are no-pull harnesses and head collars, but with a breed like yours, fit and the right choice of tool really matter. A poorly fitted harness on a Corso can give them even more pulling power. Can you tell me a bit more — roughly how much does your dog weigh, is the pulling consistent or triggered by specific things like other dogs or smells, and have you tried any equipment before?
He's about 55kg and it's pretty much constant from the moment we leave the house. We've tried a front-clip harness but he just steamrolls through it.

That makes complete sense — front-clip harnesses work well for medium dogs but at 55kg of determined Cane Corso, they often don't provide enough control to actually redirect the dog. The pulling force is just too great. What I'd recommend for a dog this powerful is a head collar rather than a harness. Has he ever worn one, or is that something you've not tried yet?
No, never tried a head collar. I've heard mixed things about them — are they safe for big dogs?

Used correctly, yes, they're very safe — and for a dog this size they can genuinely be transformative. The key is that they work by steering the head, so when the dog pulls forward, their nose gets turned to the side rather than them getting any reward from the lunge. A 55kg Corso cannot fight physics. The product I'd point you to specifically is the Halti Optifit Head Collar in size Large or Extra Large. It's designed with deeper muzzle padding than most, has a safety link that clips to the collar as a backup, and the fit is properly adjustable — which matters enormously on a broad-headed breed like a Corso. It's widely available on Amazon UK and is one of the few head collars built to handle this level of strength.
Will he just hate it and refuse to walk? My neighbour's dog went on strike when they tried one.

Most dogs do need an introduction period — putting it on and immediately heading out often goes badly. The approach that works is fitting it at home for short sessions with treats, letting him get used to the sensation before any walk happens. Usually three to five short sessions over a few days is enough. Once they associate it with something positive and realise the restriction isn't distressing, most dogs settle into it quickly. A Corso is smart, which helps — they figure out the new rules fast. The Halti also comes with a fitting guide and there are decent YouTube tutorials specifically for introducing head collars to large breeds, which are worth five minutes of your time before the first walk.
That's really helpful. Is there anything else I need alongside it?

One thing worth having is a double-ended training lead — one clip attaches to the Halti, the other to a back-up collar. The Halti Optifit includes a safety strap that connects to the collar, but a double-ended lead gives you extra security and lets you give light contact on both points, which helps with steering rather than just stopping. Beyond that, the equipment alone won't train the walk — it gives you physical control while you work on the behaviour, but loose-lead training with a Corso this age is worth doing properly. If the pulling is deeply ingrained, a couple of sessions with a force-free trainer who has large breed experience will accelerate things considerably. The Halti is your immediate solution for safety; the training is what makes it stick long term.
