Honestly? Any GSD can probably be finished as a Champion in the UKC show ring. Trent could be... and while it's great GSDs of all lines will be put up, depending on the judge, the title in itself isn't worth much, when it comes to German Shepherds. There are UKC Gr. Champions that look to me like German Shepherd mixes, and while consistency isn't necessarily a good thing (ex: American show lines at a National level), the judges could definitely do better when it comes to awarding points.
But, of course, there are some gorgeous UKC Ch. GSDs as well... though just about all of them, like Xeph said, would never make it anywhere in the AKC ring, whether it's lines, angulation (or lack thereof), etc.
However, the atmosphere in the UKC show ring is definitely a lot friendlier, I've heard. People are helpful and encouraging, while those in the AKC can be extremely competitive, and certainly "above everyone else" with their attitude. Also, no professional handlers allowed in the UKC!
Xeph, I like that Samuri bitch!! And looking at her pictures, I can see more examples of a nice, balanced American show line GSD stacked to appear on the "extreme" side...
BTW, is the AKC going to have Grand Champions as well in the future, or was that just a rumor? I thought I read about that somewhere...
