How far can you walk your 12 week old border collie?

At 12 weeks old, a border collie can typically handle short walks of about 5 to 10 minutes, a few times a day. It's important to focus on socialization and gentle exercise rather than long walks, as their joints and bones are still developing. Always monitor your puppy for signs of fatigue or discomfort, and adjust the duration accordingly. Gradually increase the length of walks as they grow older and stronger.
