I just can't ride a horse!!

I mount it, and when it loves me I try to put a saddle on it. It either takes serious damage or dies. I try to feed it to heal it, and it dies! If It does manage to survive, I hop on, and it just instantly dies! I know it isn't suffocating because there's never anything in the way for it to suffocate in! I heard the squeal of them dying for the first time and I'm like what the flip and I realized my horse died! Now this happens every time I try to get a horse ever since the most recent update.
