  • They are highly responsive and generally pick up training quickly.
  • Their sensitivity means they respond best to calm, consistent handling and positive reinforcement.
  • They may become vocal if not given enough structure or activity.

Exercise Needs

Collies need regular daily exercise to stay physically and mentally healthy. Walks, playtime, and training activities help meet their needs. While not as intense as some working breeds, they do best with consistent activity and engagement.
