My Fav Horse Despawned From Under Me!!! Can i Have it Back? :(

Help! I was in my world and going to a village. My horse and I were crossing a bridge when my game completely glitched out and when I came back, he was GONE! I looked everywhere for it and he was nowhere to be found. Mojang, can I please have my little Dill back please?

(I have no screen shot. I am very sorry)
