Hello everyone. I am looking for a breeder or importer that could provide me with a world record sized, purebred (show, working, or hybrid quality) perfectly colored (zero white) black/tan or black/red GSD with all close to excellent X-Rays and in perfect health with at least a five year health guarantee in the contract. The meaner looking he is, the better. I have had a GSD in the past so I am very experienced but unfortunately he's no longer with us. My first mistake was purchasing him from a backyard breeder. The first year and a half of his life was spent at the vet racking up over 3 thousand large. Even after many arguments with the breeder on his so called "satisfaction guarantee" nothing was done. I am looking to avoid this at all cost. The pain of loosing him has been unbearable. This GSD would be trained extensively to become my service dog as I am a military veteran who suffers from PTSD. I would like everyone's opinion on who the best of the best of the best is for my specific needs. thank you all so much.
