Darn, I don't even know how to start this...my friend's horses are in my care next door to me, which means I make sure they have feed and water. Today, I went over as I do every day, and one of her horses wouldn't move and seemed to be in pain in the back right side. Picked out the hooves and felt around for any heat and felt nothing. Even tempted her with treats, still wouldn't move. I wonder if she might have slipped and fell, hurting her back, thus the lack of movement? Or could it be colic (no rolling or kicking at stomach)? I tried to contact her (owner of horse) and the land owner (very nice guy) said he'd try too. I'm thinking that a vet is in order here and am just asking you guys out of extreme concern for the horse. She hasn't asked or shown much concern for them in a long time but I hope she steps up at this point. I'm going over before I go to work tomorrow morning and will update. Til then, I'm hoping for some of your thoughts on this. I'm not very horse savvy as far as this goes...just so you know. Thanks for any help you can offer.
