Help tracing my dog using his tattoo
To give a little back story, my dog Titan who is an all Black GSD was rescued in Colorado by my brother and two years ago he passed away so my wife and I adopted Titan. We just began doing Schutzhund training with him approx 4 months ago and every trainer we have seen asks about his pedigree because they believe that he comes from working lines. He has a tattoo on the inside of his ear but the part that has been usual to everyone is that it appears to be all letters. As best we could make out from the tattoo the letters appear to be CERLDM. Any help with this would be so great. Thank you!
