Here's my take on USA.
As a long standing member the organization has always had the goal of being a GSD organization. The take that there was a change in the club is wrong.
The fact is the only difference made was that the Nationals would be a GSD Ch. Why? The Germans didn't like the fact that USA was a GSD club and the event called the Nationals wasn't a GSD event.
The decline in numbers comes from many avenues. first, the cost of doing SchH. 65.00/year for the national club, a local club has dues to include affiliation dues to the national club and to the region it belongs to. I think I figured out last year that we needed 12 members paying dues at 250/person to cover equipment replacement, insurance, regional dues and fees, national dues, and the basic cost of one trial per year for a USA Judge.
Add to this the need to register the dogs with USA, now we need to do a helper seminar or send our helpers to one within the next year or so.
Another reason is that among dog enthusiasts they have a broader choice than they have ever had. DVG, AWDF member groups, Mondio Ring, Street ring, PSA, French ring and of course WDA.
Law Enforcement has all but lost all interest in USA due to the decline of the WPO in Germany and the fact that WDA has picked up the event and brought with it a bit of clout since the judge for the event is also the representative to the International Congress on Police Dogs, the over arching organizxation for the WPO.
An additional reason is that the GSD continues to loose ground against the Malinois as a working dog and most people in the US that do SchH are in it for the bite work plain and simple. You can track, do agility, show your dog in obedience and conformation in AKC, you can do S&R, you name it through many groups. So, if you want great bitework we see more converts to the Malinois and they go to a variety of sports/disciplines.
And here is another reason. Professionals dominate USA. It is intimidating for a newbie. They get sucked into the idea that they need to work with a pro, pay a pro, and emulate one to have any success.
There is little nurturing of people with varied interests within USA.
In addition USA's breed program is a copy of Germany's but not recognized by them. It is a tough to participte in program in the US. Travel is costly (and becoming more so) but USA seems to think it should just keep the status quo.
It needs a quick efficient breed selection program that provides a one day in and out for breeding stock evaluation. a Breed suitability test where poeple can dedicate one full day or a weekend to get a breeding licence on their animal. To promote the USA working dog breeding program as the one and only of its type in north america. The Germans don't have to like it or recognize it.
The other thing that needs to happen is that the AWDF MUST become a useful overarching organization that promotes the same thing among its member clubs:
registry and working titles and breed suitability testing. national championships and cooperation among the member clubs to produce a working model program to promote performance sports and breeding among Americans.
The plan must include things like promoting various sports and disciplines among the members by recognizing those efforts to wupport the breeds involved regardless of which program they play in.
Just my two cents on the subject.
