I dont disagree really with ace in a broad spectrum kinda way. But I aint calling anyone out on points I dont know. I dont for see any reason Kona would ever jump a 6ft fence. Unless you were in my yard and running and you jumped the fence. And well thats your ass. I know my dog pretty damn well. I have seen what she can do, will do, and well, I know my dog. I can pretty well tell you exactly what she will do in a given situation long before it happens. I suspect others do as well. So not knowing ones dog, or how that dog acts, can act, or will act, not knowing the thickness of wood, length of screws, whats on the other side of the fence, who owns whats there, or any number of contributing factors, I dont see how I can make any kinda judgement.
As a general rule I agree with ace. But in general, general is only middle of the road
