Hello all- I have been lurking here for several years and finally registered because I am dying of curiousity about my rescue dog. Two years ago I pulled and began to foster a bi color GSD for my rescue group. His estimated age at the time was seven and was pulled from a rural SC private humane society. I was a foster failure and now he is mine. Last week I was rubbing his belly and noticed for the first time a six digit numeric tatoo on his abdomen. The only explanation I can think of for not seeing it sooner is perhaps his hair is receeding or turning lighter as he is getting older. I cannot fully make it out as the last few digits still have hair over them. A military dog trainer from Fort Bragg worked with him shortly after I got him and determined he is scent trained. A friend of mine who was a K-9 officer before retirement believes that he is an import line. I have tried to search the internet to find information about this tatoo with no luck. Does anyone know what organization tatoos in this manner or where I might find more information?
