If you’ve just brought home a Belgian Tervuren 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 Belgian Tervuren is a large breed. Adult males typically weigh 55–75 lb (24.9–34.0 kg) and females 45–60 lb (20.4–27.2 kg).

Large breeds keep growing well past their first birthday, mostly filling out in the chest.
