My mare was in show shape all summer. She looked great, especially for having been a broodmare. In July I stopped working her as hard and cut back her feed, but she started to get a bit "thick" in the barrel towards her back legs. I put her back on her showing diet and exercise, but now she looks pregnant. Not pregnant like a seasoned broodmare would look, pregnant like a maiden mare would look. I have had the vet out, ultrasound found nothing, we went over diet, worming, the usual suspects, the only suggestion I got was maybe cushings, but I have a hard time seeing that if the only sign is she looks like she swallowed a beach ball. Has anyone got any ideas of what could be going on? Or helpful tips to work the belly? We already trot poles, raised trot poles, and back stretches. I just heard a rumor that there is a super secret show in October and if it's true I would like to take her, so I need to do something.
