As far as the whole show / working debate goes, I am very much in favour of breeding towards a Univeral GSD.
The only way to achieve this is to recognise that a "working" dog has many different potential jobs and that many different qualities are needed in the dog to fullfil the various job descriptions.
I've been reading with interest, the recent posts about what beeeders are breeding for, and the types of dogs they are producing. If we are not careful, we may end up with a situation where breeders interpret the requirements of a working dog from the demands of the growing sporting public - many of whome (NOT ALL) go to breeders wanting the maddest, prey monster with fight drive potential, believing that the phrase "will not out" is an accolade! How many jobs can this type of dog do? (Oh but he'll get a 100 points in Sch protection phase, oh but he won't out - well we'll zap him until he does!!))
If we go back to Max von Stephanitz we see that his vision for the GSD was for a versitile working animal who could turn his talents to anything to aid his master. To breed such an end product, Stephanitz demanded from his breeding stock (from memory) good character (nerves), stability, tractability, aloofness, willingness to please, calmness, ability to focus, intelligence, self confidence and the ability to go from the master and work on his own. Back then they didn't have all the jargon for training (compulsion, motivational, thru' drive, avoidance) Stephanitz said that a dog must work for the love and bond he has with his master and that taining is a dog's education. Of course he did also use some of the same methods we use today including prong collars etc but he never lost sight of the primary motivator for the dog which must always be to please his master (not to get his ball or a bite). I think we have lost some of this important philosophy along the way.
Of course we have all seen the problems with the dogs produced out of show lines destined for a show-public who demand the latest fashion in ski-slope or banana backs and are so far removed in character from a GSD. This isn't the answer either!
Forget US or UK show - yeuk!! But, yes, bring together (German, DDR, Czech etc) working and show lines but not necessarily through breeding them together in the first instance.
Each breeder should instead look to improving his own stock with a true versitile working goal in mind. This is what I try to do as a responsible breeder. Generations down the line, from my German herding and tracking lines mixed with top old German show, I believe I will be able to carefully but sucessfully add the blood of more working types to achieve even more versitility.
For those who will undoubtably say "why even bother with ANY show-line blood - just use the working dogs as a starting point to improve upon" I think I have a good starting point. Our German show-herding line male is protection trained, will out, HAS engaged in a real life situation, is afraid of nothing, is completely reliable with kids / puppies, is cabable of bite-inhibition to issue a warning to an intruder - so no law suits there! Only raises one eyebrow when anything goes past the gate / fence, Flips immediately into drive if I give his trigger word and flips right out again afterwards to lick my 4 year old's face, Hips - 7:3=10, level back, 27 inches at the withers, just over 6 stone in weight. Only problem is he chases cats and is deaf whilst doing so - I'll allow him that one given all the above.
My point? There is excellent blood to be had in both spheres and we should try and preserve and work with the best of it towards a common goal. Dogs that don't measure up shouldn't be bred full stop - in either camp!
