the reasone why most larger four legged critters like horses ect... sleep stanging up is because they weigh so much that if for long periods of time on their sides or on the ground they would either break their ribs or constric their lungs and suffocate.they do however lay down for short periods to rest their legs or if they are sick or injured.

It's just nature. There are so many things that we cannot understand though. Try putting ourself in their position would make us understand better
