Running is when all feet leave the ground at some point during the strides, so any animal that runs could have a similar image taken when the front legs finish pushing off the ground and the back legs are in position to start their push.

Except for humans, because we still alternate legs while running and don’t have bodies parallel to the ground that our legs would end up tucked against during part of a run. Though you could still get a picture where we’re entirely airborne if you time it right and it’s a run rather than a fast walk.

I am pretty sure this is a regular dog running and captured at this awkward time. The legs of the cat have been photoshopped out.

Nah, dogs just look weird when they run
