I'm gonna chime in here about DDR and CZ lines.
First every singe decent DDR dog was linebred on Bernd Leerburg with no exception.
The border dogs that were discussed in the previous post were police dog rejects varying from rank awful animals to timid fearful dogs. Just trash for show for the most part.
The DDr dogs have pretty much died out now except for a very few examples due to their poor hip production.
I loved the one a I had 9bred 3,4-4 on Bernd.
Many good heavy boned dogs were imported about the time the wall came down but very quickly the supply dried up. i was around buying dogs for police work at the time.
CZ dogs are often bred in similiar fashion to DDR dogs in fact it was a place the DDR dogs could go to be used as stud dogs when it was all but impossible to go from DDR to West Germany with a stud dog. So, you can find some DDR in the CZ dogs. You also find quite a few German dogs in the CZ lines even represented are some remnants of the line that produced Mutz Peltzeirfarm.
It is important to remember that the GSD's 100th aniversary was only in 1999. Hell I've been involved with them for more than 25% of their existance now. the stud books haven't opened in a long time so the dogs are all inter related so much so that even Helmut Raiser has pronounced what he perceives as a need to reopen the stud books to bring in desireable traits.
The point of all this is that the GSD is not so different from one country to another, we can thank (or bitch about) the WUSV for this. There is a reason why this organization exists and it is to foster the German vision (whatever that is currently) of the GSD.
I have owner DDR dogs, CZ dogs, German Dogs, Hungarian Dogs, GSD's from Holland, Denmark, and even France.
The differences aren't the country but the interest of the individual breeder that is producing the dogs.
The current crop of working lines in Germany isn't bad at all, better than many people are willing to believe, it is just that so few working kennels still exist.
The CZ, Slovakian, and Hungarian dogs are very often unregistered, or have a very mottled back ground and they often have more health issues.
There is no doubt that in CZ and Slovakia we have a industry now trying to raise and breed dogs for export as police, military, and detector dogs. It has spawned a very interesting situation where we can shop for dogs.
Has it changed the breeding??? Maybe a bit but I think it has more changed the way dogs are reared. The CZ and Slovakian, Hungarian kennels see their dogs going to the police and they rear them for this. The German dogs are raised as sport dogs and done by individuals who do this as a pure hobby. Dogs for sale come from this back ground and may spend a bit of time at a brokers place doing a little work to prepare them for a selection test but not much.
here is where the differences lie moreso than breeding.
For some reason people like to roamnce of their dogs origins and much misinformation is spouted about the breed from this country or that.
I find it interesting that Ed has only used a very small number of DDR and CZ dogs in his breeding programs over the many years I have known him.
That truly powerful dogs that he has had at his kennel like Otis, and Natan, and Kucho, were all west german dogs.
I have CJ (a dog with a CZ pedigree)a truly powerful dog that owes much of his lineage to Enno Berglein and old well known West German Dog.
My current dog has a Swiss mother and a Austrian father...of course the pedigree is German. But, do I start talking about the Swiss lines this, or the Austrian lines that??? No, but I might talk about the production of an individual breeder since this dogs brother was a Bundesseiger competitor last year and such breeding makes me perk up and look at what was done in that breeding program.
