Border Collies came from the hills along the Anglo-Scottish border, where shepherds valued dogs that could gather sheep with speed, focus and very little direction. They're medium-sized, usually 30 to 55 pounds, with rough or smooth double coats in black and white and many other colors. Shedding is moderate and heavier with the seasons.
Many are quick learners that bond closely with their families and stay reserved with strangers. That intelligence needs an outlet. In Glendale that can mean early trail walks, fetch at a park, trick training or puzzle toys at home. Without enough to do, a Border Collie may herd children, chase bikes or invent its own jobs. Dogs vary, so each one's energy and sensitivity will differ.
