Boxers typically reach adulthood around 18 to 24 months of age. However, this can vary slightly depending on the individual dog and their overall health. During this period, they undergo significant physical and behavioral changes.

In the first year, Boxers grow rapidly, and by the time they are 12 months old, they are usually close to their full height. However, they may continue to fill out and develop muscle tone until they are about two years old.

It's important to note that while they may be physically mature, some Boxers may still exhibit puppy-like behaviors until they are around 2-3 years old. Training, socialization, and mental stimulation are crucial during this time to help them develop into well-rounded adult dogs.

To support your Boxer during this transition, ensure they are getting a balanced diet, regular exercise, and consistent training. This will help them develop healthy habits and behaviors as they mature into adulthood.
