Foal couldn't stand up, so he was taken to the vet to try to find out why.

I didn't know this could happen either. So cute!

Squeeze paralysis.

I don't know the actual name of it, but if an otherwise healthy foal is barely moving, yeah, it's a weird phenomenon and not super common!  They often pass away as without the physio and feeding, they pass quickly!  What a cutie!
