Border collie

  Originally known as the “Scotch sheep dog,” the border collie hails from the highland border of England and Scotland. 

 Bred to think independently and at long distances from human shepherds, they have the problem-solving intelligence and strong working drive to maintain control of the flock. Chaser, the dog who knows 1,022 toys by name, is an amazing example of her breed. 

 One of the most intelligent of all breeds, the Border Collie is also one of the most challenging to live with. 

 His superior intellect, combined with his intensity and obsessive zeal for working, are his most impressive features – and also the ones that make him unsuitable for most homes. 

 This sharp-eyed, quick-thinking, fanatical workaholic has been bred for endless miles of sprinting and stop-and-go action. 

 If it isn't possible for him to work livestock, you must substitute several LONG (45 minute) walks per day, plus off-leash romps in a safe area like a dog park. Plus fetching balls or frisbee. Plus weekly classes in advanced obedience or agility (obstacle course for dogs). Yes, this is a lot 

 High intelligence does mean they learn very quickly - but that includes learning how to do anything they set their minds to. They are master escape artists who can virtually pick the lock on your gate. 

 Trying to train a Border Collie, in fact, can be frustrating, because they are constantly thinking, analyzing, and reacting to every tiny movement you make. They can be a bit high-strung and oversensitive to sound and touch. 

 You must stay one step ahead of this challenging breed, and most households are simply not up to the task.
