How do you stop a horse from biting another horse?

Answer 1

Unless the horse is pinning its ears, he/she is probaly just playing around. They probably just want the attention that the other horse(s) give them when they do playfully. To stop the biting, try a horse muzzler, sometimes called a grass stopper. They are comonly used on trail rides so that horses to not bend down to eat grass. However, use caution because the horse cannot drink with it on.

Electro shock ring on the horses wither. Press a transmitter button when the violation occurs and after a few times the bad behavior will cease with no harm to the offending horse.

Answer 2

You can try to separate the horses temporarily, provide more space, ensure they have enough feed and water, and monitor their interactions closely. If the behavior continues, consider consulting with a veterinarian or professional horse trainer for further assistance.
