When we first got Dancer, she had a HUGE mat in her tail - someone had braided bailing wire in it and left it there. We had worked the bailing wire out (I thought) and were trying to comb out the mat a little at a time. Unfortunately, Dancer went down to the pasture and got her tail hung up on a tree branch, and couldn't get loose. She must not have been there long before we found her. We had to cut a lot of her tail off in order to get her free because she had tangled it up around the branch and it was a hopeless mess.
She still has more tail left that a lot of the Appys do around here, but it had been so long before... she sure looks embarrased now!
How do horses get themselves in such pickles?
