Jumping is a must for me, not so much whilst chasing on the lamp as u can stop most things from making off through gaps with a quick shake of the lamp, most frustrating thing is [bANNED TEXT] u hav to lift a dog over every gate and fence in sight, i hav a bullx that will jump fine whilst chasing but wont jump when just passing over a gate or fence, my saluki pup clears the big 6 bar gates even without touching them sometimes so the barbedwire fences are not a problem injury wise.
