I recently rescued a said 4 year old gelding. The “cowboy” that had him said he came from Nebraska and the poor guy has a brand on his back. I just couldn’t leave him so I brought him home. He doesn’t know what good people are and we’re putting weight on him, slowly trying to gain his trust. He tries to nip at my arm, he’s pulled up his leg when I brush him towards his hind end. I don’t feel he is being aggressive. I feel that he is scared he is going to get beat again. I’ve had him for 3 days and I can now touch the forearm but still not the hind end. I have done join up with him and he does well with me on the ground as long as I don’t touch him past his girth area or below his belly. Any and all advice is much appreciated. I’ve never seen a horse this mentally damaged and I want to make sure I’m not doing any more damage.
