Running a German shorthaired pointer

Meet Mozzie, a 5 year old GSP whose all-time favorite activity is to crash the bush while chasing/being chased by the ATV. How do you run your dog? Well... If you can jog or run and in a sustained manner, go right ahead, but we've found a way to keep him amused with a few outings a week where he can tear it up on the trails. He can sustain a run at about 40-45km/h with peaks near 50, and trots along at about 35km/h for what seems like forever.
