LOL. That's great! Nice looking dog, too.
We have four dogs and aside from me taking a different one each day on my morning walk, my wife takes them on what she calls "Hillbilly Dog Walks" on a John Deere riding mower we have, riding the mower with the dogs on a long, retractable leash. She doesn't get any exercise, but the dogs can run alongside and get more exercise than just walking with me as the mower goes considerably faster than I walk.
I showed her this video. She loved the camera on the RC car and she liked your boxer.
