I really really hope you find Cookie!! I know somewhat how it feels to have a dog missing. On Christmas day I went into the dog room and only one of my yorkies was there, and I started to panic and go nuts.

I went to call my husband and when I went back to dog room she was sleeping behind the couch!
But I've had some really really close calls, my yorkies are so crafty with trying to escape. Once I was checking my mail, and I see Manolo just walking towards me. I was so shocked!! How did she get outside?! They can be so independent sometimes. I pray that Cookie will answer your call and come home soon.
May God bless you on your search for Cookie, and if anyone dognapped Cookie, I hope they find it in their hearts to return what is not theirs!!
