Mom was blowing up balloons. I was watching her. One of them popped. I peed on the floor and kept peeing all the way through the living room till myself jumped on the couch and dug my way behind a big pillow. When my head was ready to come out from its hiding place, Mom was sitting on the couch all quiet-like near me. My paws walked me to her where she petted me and talked soft till my whole self curled up in her lap with my eyes shut. Mom is very brave. When the balloon popped, she did not pee on the floor.
His point!
Following an unexpected scare, make yourself available to your dog so
you can calmly offer reassurance when he/she is ready to come to you.
