I agree on the last post about playing vs. walking. I can take my Basenji on a walk for a solid hour and he won't be very tired. Encourage a few B-500s and play a few games with my B and he'll be napping in no time.
I think the short bursts of high intensity exercises become more effective at wearing these guys out. Just my opinion though.
I totally agree. In the course of Kipawa's day, we go to an off-leash dog park so he can run like crazy. For the evening walk, we do controlled leash walking. He is definitely more tired after the off leash play time where he runs like a bat out of hell!
