So the french ring is pretty tough, huh?
How would you guys rank it against to other bite sports?
It's ranking is unique because it has a unique focus. The decoy has the obligation to exploit any weakness in temperament and/or training. Reason why the decoys have a wider array of movements than their counterparts of other sports like Sch., NVBK, KNPV, RCI, IPO, Mondio, etc.
I only addressed sports. "Real" dog training (Patrol, PP, PSD, Area Guards, etc) or training dogs for real life scenarios can make a good sport dog look bad without proper training. Hope this helps.
