Now I know that horses can take the cold, but how about extreme cold? My pony is snug as a bug in the rug in our barn but are neighbors have four horses. These horses are fenced in a little area in the back yard, and have no shelter not even a wind break! Okay maybe this isn't sounding all that bad but Thursday it was -25 degrees and that is not including the wind chill. Yesterday it was -18 degrees not including the wind chill. We drove past them and those horses looked miserable. So how cold is too cold?
