About the breed
Border Collie
The Border Collie is widely considered the smartest dog breed — an intense, athletic herding dog that needs a real job. Border Collies are reasonably long-lived and stay sharp for years.
Care basics

Exercise. This is one of the most athletic breeds. Long runs, agility, or herding work suit it best.
Senior years. Border Collies often stay active late. Around age 9 to 10, adjust activity for an aging dog.
