I recently had my horse (11 years old) get looked at by a vet/chiropractor. He was being very tight and touchy. The chiropractor had adjusted his back told me his back was locked up and the horse could not unlock it himself. The chiropractor said that massaging his back would help his attitude and riding. It does help him a lot but wanted to know better methods. Does anyone know certain massages that would help unlock him better than other massages? I have just been rubbing and pushing down on his back because I didn't know any specific things to do.
