This is a specific conversation about Dog collars — fit, material and safety — ask about yours and get one honest answer for your exact situation.

Getting the right collar on a Cane Corso before they hit full strength is genuinely smart thinking — at 8 months they're already powerful, and by 18 months you'll be dealing with a dog that can hit 50kg or more with serious neck muscle behind it. Collar fit and construction matter enormously here: too loose and a determined dog slips it, too tight causes pressure injuries, and a flimsy collar simply isn't safe. To point you in the right direction — what's your pup weighing now, is this primarily for ID and daily walks or do you have training in mind too, and are there any concerns like pulling or reactivity already showing up?
He's about 35kg already, so getting big fast. Mainly for ID and everyday walks but he has started pulling quite hard on the lead. No reactivity yet but I want something that won't snap or stretch if he does lunge.

35kg at 8 months — yes, you're on borrowed time with anything lightweight. For a dog this size and this trajectory, I'd look at the Julius-K9 IDC Powerharness buckle collar. It's a flat collar, so it keeps things simple for ID tags and daily wear, but it's built from the same heavy-duty nylon webbing as their working-dog harnesses — the hardware is metal, the stitching is reinforced, and the buckle is a proper safety clip, not the cheap plastic you get on most pet shop collars. It won't stretch or snap under a sudden lunge from a large breed. You can also clip an ID tag to it without worrying the ring will work loose. What's his current neck measurement? That'll tell us which size to go for, because fitting it correctly is just as important as the build quality.
I measured him last week and his neck is about 52cm. Should I size up to give him room to grow?

Don't size up — fit it correctly for now and replace it in a few months when he grows out of it. A collar that's too loose on a strong dog is a real escape risk, and a Cane Corso that gets loose because the collar slipped is a serious situation. The Julius-K9 IDC collar in size Large covers roughly 45–65cm, so at 52cm you're right in the middle of that range, which is ideal. You'll get the two-finger fit — snug enough that it can't be pulled over the head, loose enough that it's comfortable. Check the fit every few weeks as he fills out through his neck and shoulders. When you're consistently near the top of the adjustment range, that's your cue to move up. For the pulling specifically — this collar will hold, but I'd strongly suggest pairing it with a front-clip harness for walks while you work on lead manners. The collar handles ID and control in a pinch; the harness handles the daily pulling management without putting strain on his neck.
That makes sense. Is the Julius-K9 collar easy to find in the UK and roughly what should I expect to pay?
inparticular.ai
Yes, it's widely available — Amazon UK stocks it reliably and the Large size typically runs between £15 and £22 depending on the seller. Julius-K9 is a Hungarian brand with a strong working-dog following across Europe, so it's not a premium price for a fashion label — you're paying for the hardware and construction. Look for the listing that says IDC Powerharness collar or IDC collar specifically, as they also make harnesses under the same IDC name and you don't want to confuse the two. One practical tip: register the ID tag on the collar with your address and a mobile number, not a landline. If he ever does get loose, a mobile number is what gets him back to you quickly.
