If you’ve just brought home a Presa Canario puppy, the calculator below estimates its adult size from its current weight — personalized to your dog, not just a breed average.
Estimates combine your puppy’s current trajectory with typical growth curves for this breed and size class. Individual dogs vary — nutrition, genetics and neuter timing all matter. For health concerns, ask your vet.
The Presa Canario is a giant breed. Adult males typically weigh 110–130 lb (49.9–59.0 kg) and females 88–110 lb (39.9–49.9 kg).
