Border Collies are known as the smartest dog breed in the world.

Chaser is a 9-year-old Border Collie who knows 1,000 words… She knows nouns and verbs individually and, impressively, syntax: she can understand nouns and verbs in tandem to form an action. Watch the video and see how smart Chaser is! 🙂
