Doug,
the dog that took third at the Stud dog competition is called Branco v. Steen(something). I don't recall the second part of his name. I will dig for the whole info and send it to you.

The one is going this year, comes from Zuid Holland region and has military parents from Lituain(spl??).

Here is a link to a Ring II Rottweiler owned by a american woman that lives in France. THe dog's name is Leader.

Another Rottweiler in France that is doing Ring I is:Poker Du Château

Rottweilers that have just competed the Championnat de France Mondioring :

MR I
Phalco aus Dem Lande der Musketiere
Rox du Domainde du Mas d'Or

MR II
N'zon v. hundegluck

I am sure that there are more in France and I will try to collect them all.

About Rotts x Ring, one thing that I have to say is that almost always these dogs are MUCH lighter then the typical Rottweiler that usually go to show ring,even though one cant say that is two different lines.

And besides that, the only Rottweiler that I have seen doing Ring III in France,Billy, wasn't saving any energy. It was really nice to see it. Full speed ( for a Rottweiler) and power.
