The model uploaded the picture to Instagram on Monday but left many of her 74.1 million followers confused with the shadows in the picture, and many questioned whether it had been digitally edited.
The snap appeared to show Kendall standing on the horse's back, looking down at its head as she called it her "spirit animal".
"The magic of photoshop," suggested one follower.
Another speculated: "Y'all the horse is fake, relax." Lol
