Just like humans, horses do need additional attention when expecting a baby. If your horse is pregnant for the first time, follow these care guidelines to help provide for her needs.
Protect Her From Disease
During her pregnancy, it's essential that you only allow your mare to interact with familiar horses. Don't allow "guest" animals to share a stall or paddock with your pregnant horse. Ideally, she'd spent the majority of her time with the same two or three mares, who may also be pregnant.
