In reply to Jon Wylie: I only downclimbed the top 50m of Angel's Peak NE Ridge - where I gather its at its most difficult? But if your dog can do that I think he'd be ok. The Devil's Ridge at its technical hardest has got a bypass path. Over the rooftop, it's an easy path but completely unforgiving of a slip.
An Garbhanach has a weird bit, as well, can't remember much though.
