on a windy day, b gets teary eyes sometimes, but I just put this down to the wind. I get it too.
I would be interested to know other people's thoughts. - one night one of the ponies at our yard was pts after a very prolonged bout of colic. The horse stabled opposite stood most of the time he was ill looking into his stable with tears streaming down her face. don't know if she was crying or not, but she got big cuddles.
