Based on the image you sent, the footprints are likely made by a red fox (Vulpes vulpes). Red foxes are common in North America, Europe, and Asia. They are known for their bushy tails and pointed ears. The footprints in the image show four toes on each foot, which is characteristic of foxes. The size of the footprints also suggests that they were made by a red fox, which is typically smaller than a coyote or wolf.
Here are some other clues that the footprints were made by a red fox:
The footprints are relatively small, about 2-3 inches long.
The toes are spread out slightly, and the claws are visible.
The footprints are in a straight line, which suggests that the fox was trotting.
