When does a German Shepherd become an adult

German Shepherds are considered adults at different ages depending on their size and gender. In general, large male German Shepherds reach adulthood between 18 and 24 months, while females reach adulthood between 12 and 18 months. Smaller German Shepherds may reach adulthood sooner, around 12 months for males and 9 months for females.
