I am easily entertained, as this video will show you.
After running Cairo through some OB and then playing some two-ball fetch with him he jumped up on a 4 foot counter on my porch trying to get after his tug. My immediate thought, "positions." Anyway, I was pretty pleased with what he showed me so I figured I would share...even though he's not a pit bull. Sorry guys but Dyl-Weed is having none of the counter.
You can also use a fold out table. I have one that my trainer gave me. It has carpet on the tabletop part to give the dog some traction. Do you want me to post some pics? I don't know if it would help or not. But I am a HUGE fan of training positions on some kind of table.
