snow, wind, and dropping temps. went to blanket the horses and had a heck of a time finding sizes to fit. i own blankest from 64" to 82" but the arab doesn't fit anything in the chest, and my mare is either to fat, or grew to fit an 84" oh well, she's in a a tight blanket and the arab is held together with bailing twine. boy are they unhappy! only one that doesn't mind is my old cutting horse. blanket or no, he just doesn't care.
