This evening while eating his beet pulp, my gelding suddenly stopped eating and rolled his top lip up (flehman's response, or however you spell it..) he struck out a couple of times with his front hoof and then just stood there with his head down. My immediate thought was that it could be choke, so I gently massaged his oesophagus and kept a close eye on him. After a couple of minutes he perked back up and went back to eating his dinner as if nothing had happened.
While this was happening, I looked up "signs of choke" on my phone but they didn't really seem to match. However, I have no clue what else it would have been. Has anyone seen these symptoms in a horse with choke, or have any ideas what else it could have been?
I should probably mention that his beet pulp had been soaked for nearly two hours. I normally soak it for longer, but it seemed nice and mushy by the time I fed it.
