small, white dog running across a grassy yard at night

small, white dog running across a grassy yard at night. The dog seems to be chasing something or playing, its movements appear quick and agile. The yard is partially illuminated, possibly by a light source just outside the frame, allowing to see the grass and a few scattered dark spots on the ground. In the background, there is a blurry, dark object that appears to be a tree or shrub. There is also a dark, box-shaped object to the right. The camera perspective follows the dog's movement, keeping it in frame as it runs.
