Female Boston Terriers typically stop growing at 12 months, while males may continue growing until they're 14 months old.

All dogs are considered adults once they're a year old, but their height and size dictate what stage of growth they're in.

Boston Terriers have a significantly shorter growth period than larger dog breeds, like the Bullmastiff, which takes approximately two and a half years to finish growing.

The time difference is due to large dog breeds needing more time for joint and bone growth to reach their full height.
