The Briton, who won two gold medals at the Olympic Games in London and claimed a world record in the Freestyle Grand Prix, never dropped below second in the world rankings during a sensational last 12 months.
But her meteoric rise with Valegro could be in danger of being curbed, with doubts persisting about the horse's future.
After the London CDI, she said: "We are going to sit down, and see what happens in January. Maybe he will be sold, but we hope to get one share."
If Dujardin does manage to keep hold of Valegro, the pair seems certain to challenge for honours at the European Championships in Herning, Denmark from August 19 to 25.
Dujardin's success story began at the 2011 edition of the event, when she and Valegro claimed team gold to announce themselves on the biggest stage.
And with the achievements that have followed since, there is no reason to doubt they are not capable to winning again - if they can stay together.
