What was once a curious, bold dog, Brennan has now begun to process the outside world as wrought with seen and unseen terrors. Every sound, shadow, sudden movement, car door slamming, car alarm, trees rustling, empty blue bin on the sidewalk, trains, motorcycles, lawnmowers, anything and everything has the potential to be a threat. He is in constant flight mode. His gait is no longer one that is open and excited to explore his world, it's now in pre-flight mode. Most recently he became so terrified by an empty blue bin that he leapt up in the air, over the blue bin, into the street, and dragged me head first into the blue bin which of course confirmed that blue bins were evil. From there he panicked, and broke free running with the retractor leash smashing behind him on the sidewalk, creating an even more terrifying experience for himself. Now a walk is no longer one he looks forward to. Any motion toward the gate has him fleeing to the back yard. Once off property, his expectation of potential terrors are all around us at any given moment.
