Saint Bernards are typically considered to be mature and fully grown around 2 to 3 years of age. However, they often continue to develop socially and mentally until they reach about 3 to 4 years old. It's important to provide them with proper training and socialization during their early years to ensure they grow into well-behaved adults. Regular veterinary check-ups can help monitor their growth and health during this time.
