Little Snowy; Little Adventure!

Snowy's Puppia Harness got loosen (no longer tight and fitting) due to wearing it above the winter coat. As we walked on the station, trying to locate a pet store where I could purchase a new harness, Snowy was next to me at one second but then gone at another second. My heart went beating quick as I called out "Snowy". I looked around and towards the near by escalator stairs , I saw a small white fluffy creature standing on one of these moving automatically upwards stairs. Immidiatly recognised the creature who was trying to get down when he heard me. Very quickly I went after him through the escalator and was able to reach him. What on earth was the little creature thinking when taking the ride on the moving escalator. I know that it was a crowded spot so i am assuming that at a split second he lost sight of me. But glad that I located him on time & that I was calling out his name coz he stopped right there. Now he has a new vest to attach the leash on that I got for him today which is perfect in size on little Snowy. .
