Adorable pug baby! Go on without me, 1 of our previous set of 4 pugs would do that, she was hyper and would walk 3-4 times as much as anybody else when we all went for a walk because she was constantly running ahead, then back, out to the sides to smell, etc. Once she got tired though, flopped and wouldn't move for anything, you either dragged her or picked her up and carried her home, of course she always got carried. Our DD's chihuahua is like that too. She won't take him on long walks anymore unless the oldest GD goes with her to help with carrying.
