Well, on the old 5 mins per month rule this would equate to a walk of 25 mins!

If he is tearing around the place, bouncing off walls, well, maybe you could say 25 mins wall bouncing, then 25 mins walking twice a day!!!
I've always used the 5mins per month as WALKING time - not playing in the garden/acting the fool/training to sit/stay/come/bounce the ball time!
I don't know that this is the answer you wanted - but it sounds as if you need and extra energy boost yourself , in order to keep up with your pup - can't help there, I'm afraid ! :D :D :D Good luck!!!!
