I am going to have to call it a honourable draw as I have a close call with both. I have to admit to giving a cow a good slap around the face as he was getting a bit too pushy, that seemed to make him back off a bit. The horses we met only a few months ago seemed hell bent on eating my rucksack so they got a walking stick around the ear just to show who was in charge.
I feel that running away is probably the worst thing you can do as they want to join in the chase.
