Yikes, chick bea that really could have been a tragedy. Mine wear blankets at times in the winter too and i'd never thought of that happening. One time though when i boarded my mare, she got a line of fencing(tensile wire) wrapped around her leg and couldnot move. She did not panic, i happened to stop by early that morning on the way to work and found her just standing still like a statue. The owner of the place was mad that i had actually cut the wire off her leg, it was wrapped so tight i was lucky it did not cut off circulation. I keep them at home now and eventhough it means more work, i love looking out my window seeing them every morning.
