Swimming with a horse
Swimming all horses can swim, and like dogs, they don’t need to learn to swim.
Crossing a river, the rider will immediately feel when the horse loses its footing and swims; he must slide off it and grab the mane or neck. The rider can control the movement by carefully leading the reins. And until the horse reaches the opposite Bank, it should be sent by voice.
If one obedient horse floats forward, the others will follow without delay.
