Long story medium- Was buying a house that had 3 horses in back, realtor leaves and this finny drops to her side and just lays there, with futile attempts to stand every minute. I comforted her and did my best to call the owner of house, and I got desperate so I shoveled a trench along her back (she was pitted against barn wall with hooves facing barn) and then swinged her feet until she swinged over herself and then stood up after 30 minutes of being on side. I hugged the crap out of that horse and never felt more relief, but I'm worried after the owner arrived claiming she had some sort of worms in the past, has a dirty wound under chin and a few other issues. She claimed they weren't keeping the horses, even though i make good money and ill own the horses current home/stable soon, I'm scared to offer to buy her because the heartbreak of just the past 30 mins was so awful, and I'm worried of overwhelming myself with horse ownership. I was a stablehand in the past and I could handle the work, but is taking in an already sick horse impossible for a beginner owner?
