You should be in charge of the Olympic Committee and make it happen.
We could make it a multi-skill event by having the 50 yard dog chase dash after the fence jump.
I would go strictly by time + fence height: 7.0 feet + 5 seconds = a score of 12. It would be possible to add a panel of judges for style, but I’m sure the Mexican judge would cheat.
If the dog catches you, it simply adds to your time as you roll toward the 50 yard mark or drag a “dog-leg” to the finish.
