Wild dogs? Lived in the Uk most of my life, currently live in the middle of snowdonia national park and less then 3 miles from a zoo. Have yet to see wild, feral or escaped preditors!
I had one nasty farm dog try to nip a horses heals, a schooling whip rapped accross its nose soon sent it home with its tail between its legs.
If I Came accross something nasty like an escaped preditor then I would expect my horse to flee.
Do escaped monkeys count as preditors? We've got a few of them round here!
