Sorry, I don't have any pictures to show on this topic... yet. But it's funny how every horse is so different and some show right away, and others you wonder if the vet was right when he said your mare was in foal. Our very first mare that my parents bought when we were kids was bred to a very nice stallion prior to us taking her. The mare appeared to go into heat, not once, but twice, after being bred, and as it was getting late in the breeding season, we were not able to breed again until the next year. So we thought, oh well, she didn't catch. Throughout winter and early spring, she looked like she had put on a few winter pounds, but nothing significant. And then one day, her belly dropped and her udder started showing. We called our vet, who had seen her a few months prior for an unrelated injury, and he couldn't believe the difference in her size. Sure enough, she was about 3 weeks to term.
