Should you ride a horse in the rain?

no because your horse could possibly slip and injure either you or your horse. it can also rust metal tack and soften your leather tack.

sometimes you can if it's a short distance.

You should ask your instructor if you are educated enough to ride in the rain and if you have to ask him/her what to do or how to control the horse.

And if you are riding your horse in the lake you should use a halter and lead rope.
