So, I'm asking this question because my horse has suddenly shown up lame. It was a rainy day so I let her run in the arena at 3 and she had a nice little back and forth with her buddy and she was fine when I walked her back. At 7 the barn help called me and said she was dead lame and she is. She doesn't tippy toe as if the bottom of her foot is sore, she actually has it lifted up and sometimes puts the front of her hoof too far down and then it bends completely. It's like her front tendon is sore and she's not using it. She has a little warmth and a tiny bit of swelling just above the hoof. Very recently I've had some conflict in the barn with someone who always gets her way and I'm finally standing up for myself. She is an angry person and has been doing little things to sabotage and "punish" me. To even think she would injure my horse is not something I want to think about but could someone make a horse lame? and how?
