The Czech showjumping rider Emma Augier de Moussac (pictured with another horse), who lives in France with her business EAM Sporthorses, had to say goodbye to her 1,60m-jumping mare Bella Brown today. The Dutch-bred daughter of Van Gogh suffered from a brain tumor that was slowly affecting her optical nerve, which would have led to total blindness in time. The rider said goodbye to her mare in an emotional post on Facebook.
