I have a 14 year old mare...i have had her about 2 months. Here latley when we try to ride her she acts up a little but not too bad unless my husband is on her. When I try to brush her and I get close to her belly she will try to bite me which is not normal for her. She is a really calm horse usually. And 2 days ago when I was watering her her tummy towards tje back she has a buldge on both sides and it was moving like crazy...i stayed and felt it and watched it for over 20 min. It was crazy. A friend came over and said she was not pregnant but he didnt see what I saw earlier...i am still convinced there is somethng inside or am I just crazy!!!
