When do Border Collies calm down?

Border Collies start to calm down at around two to three years old. As they mature, they often become more manageable and focused, making them easier to train and live with. However, Border Collies tend to have teenage antics and can remain quite active well into late adulthood.

Remember, Border Collies are high-energy dogs who require a lot of exercise. If you want to adopt a Border Collie, make sure you’re prepared to meet their high-energy exercise and mental enrichment requirements.
