Never lifted a dog of mine over a fence yet, start that caper and they become reliant on it, if they cannot clear gate or whatever, leave em to it, they will find a way
My apologies, i should have made it clear, my dogs do bunnies only, perhaps i shouldnt have replied, love it always gets one biting, thats sad that is, you say whipps not tough enough, i say, watch this space
