He absolutely loves to pull. He'd make a good sled dog. But - I don't know how to use that to our advantage.

I think I'll go figure out some way to use the 4-wheelers to exercise him. Thanks a bunch for all of your input.
I'd be worried about using a leash on the ATV, too easy to get pulled off or for Max to hurt his neck.

I use a 4 wheeler to train my dog team in the no snow months. Get skijoring line, a big clip and a proper pulling harness for Max. Clip the line to the front of the ATV and go. Let him set the pace.
Getting him to stay out front might take some work, but once he gets it he'll probably have a great time.

I can send you some links for getting a line and harness if you want.
