Alert!Looking for lost Chihuahua~

Our 6 month-old Chihuahua puppy disappeared from our back patio about 45 minutes ago. We live in the village of Rhinebeck, across from the Mobil station on East Market St. She has NEVER wandered off. She was only unsupervised for about 3 minutes. She hates the snow/cold and it was right before dinner time, all the more reason she would never have wandered off. She will not even walk in the snow. Her name is Nora and she is wearing a collar with her name and our phone number. We have alerted our neighbor and the Mobil station. Please alert us if you have any information or ideas on how to pursue finding her. Thank you, Karri Wolfe 845-849-5646
