It normally happens because of a mistake.. but it CAN happen because a dog has 'settled' by next class
It has happened to me... with Ollie (who else lol) I was placed.. but low in the line up.. and actually thought about withdrawing from next class.. but I figured Ollie needed the experience... as it happens he took a 1st. in his following class.. and I queried it...
The judge explained to us that I did have the superior dog, but on her 1st assessment, she could not go over him properly because he was too playful.(Bouncing). in this class he had settled, and allowed her to go fully hands on.. his movement got him a place in the 1st class.. his conformation and movement got him his better place in his 2nd class... beating 2 of the dogs which beat him in his 1st class...she was happy with her decision and stuck with it
her critique in the dog paper also clarified her placings...
