Rescue, take in, get free whats it matter it is one less horse, dog, cat that is starved abandoned, mistreated, or slautered. This lovely horse now has a loving caring home and a future. That in my book is a gold star for the good guys in this case the OP and friend. Its Xmas the season of good will kindness and charity, if you can i say Do it. I cant have and dont want a horse i wouldnt know what to do with it but I only have rescue dogs, more loving protective and loyal dogs i never have found. Im sure this horse will turn out to be a star in his own right and provide many years of pleasure to his new owners.
Lucky Star
Lucky because he was in finding you
Star because a Star led the way to a stable many years ago for those who believe.
