We stopped by our son's house a few days ago and got treated to some play time with their puppy.
Mac (short for McGruber) is a mostly Border Collie rescue who is now eight months old. Border Collies are working dogs, bred to high energy and intelligence, who demand exercise and attention. Things can get ugly fast if you fail to meet their needs.
A tennis ball or a frisbee will keep their attention until they drop from exhaustion, which usually doesn't happen until at least two throwers have been worn out.
Playing ball with Mac brought back memories of Scotty, the Border Collie we got when my son was four years old. Scotty was a grandson of the famous Wiston Cap whose sire had been imported from Britain by a local breeder. I asked my sons, then 4 and 8, to give him a Scottish name. "Let's call him Scotty." Thank you Star Trek!
Mac is a delightful dog. Now if my son and daughter-in-law don't flunk obedience training ......
