when my dog was here she could make the squirrels jump off the peaks of my neighbor's roofs. At least 12 feet.
I always wondered why they got so scared since my dog was on the ground and behind a 6 foot fence with no chance of ever getting up there, but they ran and flew like little supermen.
They spread out all fours like a mammalian kite, hit the ground and kept running..
Perhaps they might be thrill seekers, but I just don't see the need to induce it upon them.
