What a nightmare! Am guessing the problem lay in the fact she had a young dog on a lead with her. I have never heard of horses deliberating attacking anyone before and have never felt any threat from them (unlike frisky bullocks).

I do hope your elderly friend makes a speedy recovery and is able to enjoy her new dog.

I had a very scary incident with a horse in a field by Chrome Hill once..it just took against me out of the blue, charged and reared repeatedly. Fortunately I had my camera tripod with me and extending the legs and waving it enabled me to get out of there...but I've never trusted horses since

That's dreadful, I'm sure you're right about the dog being relevant sadly.

I have only ever been threatened by a horse once, years ago, when I crossed a large sloping field and didn't realise there was a mare and foal ahead of me, and a stallion behind me, which galloped up behind me and started to rear up. Amazingly turning and facing it with a loud "woah" (seriously?) was enough to stop it, but I have been wary of horses since then.
