It might be worth having a rethink, and buying in turkey, I have friends who left smaller and sentimental items in a family members loft and brings some over every time they go to uk, or have people coming out. Many Kennels in the uk arrange all the travel docs that your little (ha ha) dog needs. I also believe that you can go to the customs police here and get permission to bring used goods into turkey, i know you must keep the goods for 5years, might be worth a visit to the british consulate to get the correct and most up to date information. Hope you dont mind my comments and can i wish you all the best for your new life in Turkey.
