The breed
How Big a Cane Corso Gets
Adult height and weight, what they weigh month by month, and the mistakes that cost a big dog its joints.
A male Cane Corso stands 25 to 27.5 inches at the shoulder and weighs 99 to 110lb. A female stands 23.5 to 26 inches and weighs 88 to 99lb. They reach full height at about 12 to 14 months and keep filling out in chest and head until two and a half or three.
Those are the ranges for a purebred, and they are tight enough to plan around. If you are looking at a cross rather than a purebred, the honest range is much wider in both directions.
Month by month
| Age | Male | Female | What’s happening |
|---|---|---|---|
| 8 weeks | 15 to 20 lb | 13 to 18 lb | Leaving us. Four meals a day |
| 3 months | 35 to 45 lb | 30 to 40 lb | Fastest growth of its life |
| 4 months | 45 to 60 lb | 40 to 52 lb | Teething. Everything goes in the mouth |
| 6 months | 65 to 80 lb | 58 to 70 lb | Looks adult, is not. No forced exercise |
| 9 months | 80 to 95 lb | 70 to 82 lb | Lanky and unfinished. Normal |
| 12 months | 90 to 105 lb | 80 to 92 lb | Height nearly done, width has not caught up |
| 18 months | 95 to 110 lb | 85 to 95 lb | Growth plates closing |
| 2 to 3 years | Filling out | Filling out | Chest and head finish last |
A healthy puppy can sit outside these figures. What matters is the shape of the curve and the condition of the dog, not hitting a number in a table.
The awkward stage nobody warns you about
Somewhere between nine and fifteen months your Corso will look wrong. Leggy, narrow, head not filled in, nothing like the dog you thought you were getting.
Nothing has gone wrong. Height finishes long before width does, so there’s a stretch of months where the frame is there and the body hasn’t arrived.
The damaging response is to feed more. You can’t feed a dog past its genetic frame, so the surplus becomes fat, and fat on a skeleton that has only just finished forming is the exact load you spent a year avoiding.
The first eighteen months decide the joints
Growth plates are soft cartilage at the ends of the long bones. While they’re open they’re the weakest part of the skeleton, and a young dog this heavy can do lasting damage doing something an adult would shrug off.
- No forced running. Not beside a bike, not on a treadmill, not distance. Free play at the puppy’s own pace is fine, because a puppy stops when it’s tired and a puppy on a lead beside a bicycle doesn’t.
- No repeated jumping down from a truck bed, a deck, or the back of a car.
- Carry it on stairs until about four months, and put a runner on hard treads after that.
- Keep it lean. The single most useful thing you can do for a big dog’s hips.
- Large breed puppy food. Controlled calcium matters here, and it’s one of the few places the specific product makes a measurable difference. More on that.
Ask your vet at the twelve-month visit whether the plates have closed. It varies by dog, and it’s the point at which the restrictions stop applying.
Predicting an adult size
The parents are a far better predictor than any chart. Ask us what the sire and dam measure at the shoulder and what they weigh, and you’ll get a better estimate than a formula gives.
We’ll tell you honestly, including when the answer is that a puppy is likely to finish smaller than you were hoping.
Why the finished size is worth being sure about
Two practical consequences, and both are easier to think about before the dog arrives.
The first is the house. Stairs, a second-floor flat, a car boot and a crate all look manageable at eight weeks and different at eighteen months. Buy the crate at adult size with a divider rather than twice, which is on the list of what to have ready.
The second is money. Food, medication, preventatives and anaesthetic are all portioned by weight, so a hundred-pound dog costs several times what a small one does for the same treatment across a nine to twelve year life. The annual and lifetime figures are set out here.
Ours are weighed daily from birth and we will tell you what any particular puppy is doing against these ranges. The puppies here now.
