Diana, yes there are wrong doings in UKC, just as there are in AKC. Yes, there are handlers, and I've seen them. And yeah, all they have to do is put their name on the dog. But in general, there is a lot less of that going on. (I had said less political, not non political. lol) At least there are written rules against it. The integrity of the people showing is another story. I guess I can't speak for the people who run the shows either, haven't been to enough. They are truly geared towards owners and family dogs so yeah you're going to get some backyard people and yahoos. lol While AKC has a much more high class stigma to it, there is a lot of crap that goes on at those shows too. I've seen PM dogs that get put with a handler and finish.
An organization is only as good as the people who are involved in it. There are some very respectable people in UKC, but yeah then there are others too! Most of the folks I see at UKC are AKC folks. All the sighthounds I've ever run across have all been AKC people.
Look at AKC, we can prove there are registered dogs with false pedigrees yet they do nothing. And while they're much bigger and stronger, things can be said for a lack of integrity there too, both in the show ring and the registration department. I'm certainly not trying to knock either registry, just point out some impressions and differences of each.
