One of my boys escaped during the ice storm a year and a half ago and was gone for 3 days. Needless to say, I was a mess, as I am sure you are now. Our neighbors found him under a wood pile, safe and sound and warm. Not a scratch on him, and we live way out in the country where there are lots of different animals running wild. (coyotes) We were without power for 7 days, so you know how bad it was. Dogs are survivors!! Even little tiny ones, remember, they dont know they are small. Mia will be back, I feel very confident. My puppy prayers are with you! Let us know when she returns.
