Play or distress? Keep body language in context
A play bow can be an invitation. A tucked tail can appear in more than one context. Read the scene instead of using a single shape as a verdict.
What enjoyable play may look like
Cornell describes loose, wiggly movement, bouncing and play bows in a typical happy episode. The Conversation discusses play invitations and pauses. These clues can help you describe what you saw. They do not prove that every fast movement is enjoyable, or that a dog cannot be injured while playing.

Why one feature is not enough
Cornell notes that dogs may tuck their rear and tail during playful running, while frightened dogs may also keep a tail tightly tucked and appear tense. A photograph of one posture loses the movement and situation around it. Record the combination without pretending that a single feature settles the question.
Take distress seriously
Apparent pain, fear or anxiety are reasons to seek veterinary help. The Conversation also advises help when the behavior is prolonged, difficult to interrupt or causes injury. There is no result on this website that clears a dog medically or supplies a safe period to wait.

Do not stage a test
It is not necessary to provoke an episode to see whether a dog looks playful. A staged chase can change the behavior and add risk. If you already have a useful observation, describe it. If you missed what happened, say that you missed it instead of recreating the event for a better clip.
Keep the environment question separate
Even when movement seems playful, check exits, footing and nearby people. When the dog seems distressed, clearing an obstacle is not a substitute for care. The two questions run alongside each other: what does this space need, and what help does this dog need?
