Okay, so my horse Sugar has been looking big lately and me and my aunt think we know why...A couple days ago our neighbors 2 stallions got out me and my aunt found out from our neighbor, we always let Sugar roam around our property and our neighbor said she saw the stallions on our property our problem is that we don't know if she is pregnant or not is there any way to find out? And if she is what do we need to do to get prepared?
