I saw a horse at the track with extremely floppy ears, but I couldn't find a whole lot of information about it online. I read somewhere that it can be caused by a deaf horse not swiveling their ears to listen to things, and therefore losing muscle mass. Is that true? Does it usually make them flop this much?
It looked like he could move them a little bit from side to side, but I don't think he could pick them up at all.
I've heard of horses having floppy ears after an injury destroyed the nerves in the ear, but what are the chances that both ears would be injured in the same way?
