Not sure who needs to see this, but if a Service Dog starts backing into you, pushing you away from their handler, or they sit down at a leash distance from their handler
They are performing a task known as "spacing" or "blocking" that helps reduce or prevent anxiety in their handler.
They are NOT "asking for pets" or being disobedient or asking to be spoken to. All you have to do is stay back from the dog and handler.
This is not a capslock PSA because I'm not sure how many people that don't have a SD actually know this is a trained task.
