Mob Issue - Horse Cannot Be Rode On

It took a while, but I tamed a beautiful horse in Minecraft. I spawned a saddle and armor for the horse. As well as that, I spawned armor, a sword, a bow , and an arrow (All were enchanted except for the saddle & the arrow) for myself. I was ready to leave so I attempted to ride on the horse. Instead I would face away from it while the horse popped out hearts. I tried this numerous times until I decided to turn to the horse, take snapshots & send it to Mojang!
