Great Dane Adult Dog Wanted

My daughter had her black female great dane taken on the 8th february 2010. She is desexed and microchipped and was wearing a collar and tag with her name and phone number on it. They have tried every outlet to get her back but no luck. I thought you may send an email in case someone tries to sell her. Her name is Ellie and just a beautiful dog. We all miss her so much and her family is distressed she has gone.
