How to train a dog to take a flying leap off a dock is beyond us. But that doesnt matter plenty of other owners have tapped their best friends athleticism, turning them into first-class jumpers. At DockDogs, canines from all over the country will compete to see who can launch the farthest off a platform. Local dogs are welcome to compete, and the event will be televised on the Outdoor Channel. (Being on TV for having a badass dog is better than not being on TV at all, right?) 8 a.m. to 5 p.m. Friday and Saturday, 8 a.m. to 4 p.m. Sunday. Discovery Green, 1500 McKinney.
