Here's a horse injury that you might not think of until it happens.
Most of us out there have gotten our tongue stuck on something cold, even if only momentarily. I admit that I once lost a bit of the end of my tongue to our freezer.
The other evening, I was rubbing Lena's nose and lips and felt a dime-sized (or so) sore there. I got her to hold still so I could see it and it looked an awful lot like she had ripped off part of her lip when it got stuck to one of the metal bars around her paddock. (It's been really cold the last week or so, and the bars had ice on them.)
I can only imagine her reaction at having that very sensitive and flexible top lip glue itself rather firmly to the bar. Hopefully, it was less painful for her than removing my tongue from the door inside the freezer was for me.
I did check her tongue, too, which appears to be unscathed.
She seems to be healing fine, and I can only hope she has learned the same lesson the rest of us have about cold things and moist body parts not mixing well - though she probably has less of an embarrassment factor than humans do. Maybe.
