Mini Mare might be pregnant? Gr gut?

She's awful cute! If you really need to know if she is preggers or not the vet should be able to tell you. Has she been wormed lately? She doesn't look wormy but a heavy worm load can make their belly look distended. If she is on hay 24/7 or even all day she could just have a hay belly. Get her a buggy and start driving her for excersise to work off some of the excess.
