Border Collies
The Border collie, like the Australian shepherd, needs to have a job. They’re highly intelligent and are able to keep up with any activity you throw at them.
If you don’t have animals on a farm or ranch that need to be looked after, get your Border collie involved in agility or flyball. Agility tests their intelligence and speed as well as accuracy over a predetermined course. Flyball is a relay race between two teams of four dogs and Border collies excel at this exercise.
