Sorry to hear about your dog. We certainly know how you feel having been through the same thing more than once. Last year we had to have our 15 year old bull terrier put down. He was part of the family. We had gotten him when we lived in Swaziland and he had traveled back and forth across the ocean with us several times. If you have not seen the Rainbow Bridge then type in and search for one of the links, I think you will like it.
Hope to see you on Saturday at the GTG, still not sure we will make but hope so.
