I see the rise in popularity of Czech/DDR/any working line shepherd being a really bad thing. The novelty of having a 'hardcore' dog, who's parents 'were police dogs' (yeah right) will just be too much for many people to pass up. I mean everyone likes the idea of a big mean dog who'll protect its family right?
Backyard bitework training will be on the rise, and the unstable/improperly trained dogs will cause problems in public (think - nervy fear aggressive dogs, with inexperienced handlers, taught to bite other people. What could go wrong...) Legitimate training avenues (Schutzhund, French ring, PSA etc.) will be blamed and eventually the ignorant public people will boycott their existence.
"Why would you teach a family dog to attack!"
"There's no need for such training to be done outside of police work"
GSDs (and Working line dogs especially) already have a bad reputation, and now that everyone and their mother wants a 'dark sable DDR' who will protect their family in these uncertain times, BYBs will have a field day selling exactly what the uninformed want.
Of course this is entirely speculation, and I seriously hope that I am completely wrong. Good breeders care about who their puppy's live their lives with, but it's the BYBs that I worry about, as well as the impulsive puppy buyers who don't do their homework and want one NOW.
I haven't mentioned SLs because they are so yesterday. Today is the day of WL shepherds - 'real GSDs' as I've seen them called on here by a few. And I'm sure that's exactly what the BYBs will say when they advertise them.
EDIT: Just realised how ambiguous my first line is. The fact that DDR, Czech and other working lines are being maintained is excellent, and I hope this continues. My concern is what happens when in-discriminant breeding practices of these (along with other) lines by crappy breeders leaks out to reach joe public, and all those people who think they know how to train a protection dog with absolutely zero experience. SLs won't cut the mustard because they 'don't have the drive', hence why I think WLs heading towards being in vogue
