I don't see that as animal abuse... def. reckless driving!!!

If he wasn't forcing the dog to run, or dragging it, then its not abuse, IMO. I use to run a 200lb rottie tied to a 4 wheeler so I could tire him out, so I could then train him. The 4 wheeler was a last resort. I tried choak chains, halters, thin metal rope like choakers & nothing worked on that beast of a dog. He would drag 2 of us across several yards until we could no longer hold on to him. Then getting him back was anything but easy. it was only a matter of time he would be hit by a car, attack a dog, or was shot (we were out in the country).

The 4 wheeler was a blessing! It was something he couldn't over power & he was finally in control. Took a few weeks to get him semi trained to the point we didn't need the 4 wheeler anymore. Then a few months later our town got a Prong Collar. We bought it & that dog learned real fast not to pull. He was a wonderful dog, just completely out of control due to lack of puppy training.

Oh & he was NEVER dragged by the 4 wheeler. There was 2 of us on it.. 1 driving & the other holding raw meat to encourage him to chase us. We gave him the raw meat as a reward for chasing us. The leash was really long so if he stopped suddenly we had a good 20ft to stop before dragging him, which never happened as the person holding the food was vocally in control of the speed.
