I don't how they do it, but the Eastern Euros sure do produce some gorgeous Rottweilers, though I do realize that many breeders/enthusiasts who're into SchH will tell you that most of those males are too big to be truly competitive [what a run on sentence!]. But I happen to like the looks of the Eastern Euro dogs, including the bitches, who tend to be more substantial than the tiny runts most AKC and American breeders pump out. My bitch was bred from Eastern Euro stock [Crni Lotos, etc.] and has the substance many bitches lack. When I see too many 22" bitches in the ring, lacking all bone and heads like Dobermans, I cringe. My guess is, eventually the bitches will come up in size as more Americans import dogs from places like Serbia, Bosnia, Croatia, Hungary & Yugoslavia.
On a side comment, German breeders still produce top dogs for both show and work, obviously, and they remain the gold standard if you ask me.
