Honestly?

I wouldn't - without knowing the history of the horse and the gaining the owner's permission. At my old house there was a public footpath that run by the side of the field and my pony at the time had a history of laminitis which meant that his diet and managememy needed to be very strictly controlled. In the summer, he would have to be put in a starvation paddock - and it was a complete nightmare with well-meaning bypassers trying to feed him with what they thought was 'the odd treat here and there'. In actual fact, the 'odd treats' were potentially very, very dangerous to his health.
