That would be some dog!
Mine is 5 years old from a line East German dogs generally bred for guard duty and Shutzein(?). The dog is lean and beautiful.
And a lot less than 7,500.
Dogs are bred for tasks, not just for looks. The wrong breed in the wrong home is a challenge for everyone.
I got my dog from some Russians in the area. The parent dogs were from East Germany. They advertised them as german shepherds. When we talked to the owners, they said the parents were brought from Russia, and were considered East German Shepherds, and while the parents were “registered”, the puppies were not. That was ok way me, as I wanted a big dog, with a big bark (to scare strangers off), that was smart. $200, and I got Titan. Really smart, really a good companion, but hates the heat and loves the cold. A little research recently, and I see pictures of of the ‘breed’ Eastern European Shepherd - (VEO Shepherd). They were german shepherds bred in the 1930’s-1950’s in the USSR to be bigger, cold resistant Shepherds without the dysplasia problems of the GS. I looked at some of the pics after I read the description, and said ‘yep, that's him. Scary looking (his face looks like a mask with wide silver cheek fur), big (30” high at withers), REALLY long when he lays down, but loyal, doesn't bark needlessly (although he's spoiled and does his share of whining), loves to go out and roll in the snow (and hides out in the basement in the summer).
I'd recommend those to anyone looking for a Shepherd as a pet. He has no joint problems, only had ear mites when we got him, and at 7 yrs old had his 1st problem - staph infection on his chest. 3 wks antibiotics and he was just fine.
