Jacks are by far the most intelligent breed. However they are certainly not for everyone. You’d better know what you are getting into with them. It is also disturbing to see Border Collies getting popular. Definitely an intelligent and difficult breed. I hate to see them getting popular.
Yep, I'm glad to see my favorite breed isn't on the list.
The worst thing in the world for a dog breed is to become very popular, especially when the breed is a star of a movie or TV show and every kid wants one or, worse yet, becomes the favorite of gangsta wannabes.
