Just a suggestion….if you are going to try someone else’s blanket on her, tie/pin/secure an old sheet around your horse first so you don’t transmit stuff between horses. The store tells you that when you buy a new blanket and may have to return it for incorrect fit. They don’t want any dirt on the blanket and you certainly don’t want stuff from another horse on your horse and vice versa. Again, google blanket fit and see if there are any suggestions there. You don’t want the blanket so tight that you can’t get your hand in there but you don’t want it so loose that a truck will fit. Good luck!
