This is a specific conversation about Dog training — equipment and tools that help — ask about yours and get one honest answer for your exact situation.

A 13-month-old Cane Corso is at one of the trickiest stages — still adolescent and testing limits, but already carrying serious adult strength. Good training tools amplify good technique, they don't replace it, but the right equipment makes a real difference when you're managing a dog this powerful. To point you in the right direction: what are you specifically training for right now — loose lead walking, recall, general obedience? And what have you already tried in terms of equipment?
Mainly loose lead walking — he just pulls constantly and I genuinely can't hold him safely. He's about 50kg. I've tried a standard flat collar and a front-clip harness but he just powers through both.

That's a really honest and important thing to flag — at 50kg and still adolescent, a Corso who's committed to pulling is a genuine safety issue, not just an inconvenience. A front-clip harness is often the first thing people try and it does work on a lot of breeds, but on a dog with this much drive and chest muscle it often just redirects the power rather than interrupting it. Can I ask — is he pulling towards things (other dogs, people, smells) or is it more general forward momentum on every walk?
Bit of both honestly. He lunges at other dogs but also just pulls the whole time regardless. My arms are done by the end of a 20 minute walk.

Right, so you've got two overlapping problems — constant opposition reflex pulling and reactive lunging — and on a dog this size that combination is what leads to people getting hurt or giving up walking altogether. For a dog like this, I'd recommend the Herm Sprenger chrome prong collar. It has a reputation that puts people off but it's genuinely one of the most misunderstood tools in dog training. Used correctly with a loose lead, it communicates through pressure in a way a flat collar never can — the moment he pulls, it self-corrects, and the moment he stops, it releases completely. It doesn't require you to out-muscle him, which is exactly your problem right now. The Herm Sprenger specifically uses rounded, welded links that sit evenly around the neck — it's not a punishment device, it's a communication device. You'll want the 3.25mm link size for a dog his size, and it must be fitted properly, high on the neck just behind the ears. I'd strongly suggest your first few sessions are with a trainer who knows how to fit and use it, but once set up correctly most owners see an immediate and dramatic change in pulling.
I'll be honest, prong collars always seemed a bit harsh to me. Are they actually safe for a dog this age?
inparticular.ai
That's a completely fair instinct and worth addressing properly. The concern usually comes from seeing them misused — fitted too loosely, left on all day, or jerked hard. Used correctly, a well-fitted Herm Sprenger prong collar distributes pressure evenly around the neck rather than concentrating it on one point like a flat collar does when a dog hits the end of the lead at full speed. At 13 months his neck and skeletal structure are well developed enough for this to be appropriate. The honest truth is that a 50kg dog repeatedly slamming into a flat collar or front-clip harness is more physically risky than a prong collar used as a communication tool on a loose lead. That said — if you're not comfortable with it, a Dogmatic or Halti headcollar is worth considering as an alternative, though on a determined Corso some dogs resist them strongly and they don't suit every dog. The prong collar is my first recommendation because it works with his physiology rather than against it.
That makes sense. Is the Herm Sprenger easy to find — and do I need anything else alongside it?

It's available on Amazon UK — search for Herm Sprenger Chrome Prong Collar 3.25mm and make sure you're buying genuine Herm Sprenger, not a cheap imitation, because the link quality really matters. Alongside it, get a sturdy 1.2–1.5 metre leather or biothane lead — nothing extending, nothing bungee. You want direct, immediate feedback in both directions. And honestly, one or two sessions with a balanced trainer who works with large breeds will be worth more than anything else you can buy. The collar is the tool, but your timing and body language are what make it work. Once he understands the communication, most owners find they barely need any pressure at all within a few weeks.
