Royal Windsor Horse Show first started in 1943 to help raise funds for the war effort. It has continued to run every year since with and is now the only show in the UK to host international competitions in Showjumping, Dressage, Driving and Endurance.
Dogs have not been allowed into the showground since 1944, this is because at the first show in 1943, a lurcher stole a piece of chicken from King George V’s lunch plate. The Committee found this so mortifying that they have banned dogs from the showground ever since (true story!).
