According to Berg, "Groups of parkour practitioners all over the world have been turning the walls and roofs of buildings into urban training courses and jungle gyms. And now, dogs are doing it, too. Yes, really."
"Meet TreT, an American Staffordshire Terrier from Ukraine known as the Parkour Dog. As this video shows, TreT is adept at jumping off of walls, climbing fences and doing sweet turnaround moves on building corners and tree trunks."
As Berg notes, "TreT's trainer has a website offering to share wisdom about how you, too, can train your dog in the acrobatic arts of parkour."
