where the judge and a dog came into the ring in say post graduate class and it was fidgiting only standing still for milli seconds stood on the table ok but now and again bounced when walking but eventually settled down etc so it could be assessed.

if this was a puppy you would proberly think oh puppy behaviour and think nothing of it,

but what if it was an older dog in the pg class but it was the dogs first time showing but you as a judge what not know this  what would you think ?
would you place the dog, or would you just think that dog needs more ringcraft and should be better than this or would you forgive the dog for being bouncy etc

The judge is there to judge the dog, not the handling. If the judge sees enough to assess the dog's conformation and movement and likes it, then I imagine the judge would place the dog, but maybe have a word with the handler after the judging.
However, some judges don't seem to have any patience and will penalise poor handling - I suppose time pressure makes a difference.

I think if in the milli second I got a glimpse of everything I was looking for I would place the dog. Similarly if we got some really good movement between the bounces I would place it. Plus have a friendly word with the handler...something on the lines of.."gosh hes a bouncy wee thing, keep up with the ringcraft and you'll have a lovely dog" Enough to make them realise the dog was work in progress but encouragement to keep up the training.

I've been under judges that are pushed for time and unforgiving to dogs that only want to have fun....but yes they need to access the  dog, quickly and efficiently or else they take 4 hours to judge what should have taken 2 hours....been under them as well lol.

If the dog ticks the boxes and deserves a place then it deserves a place.  As other posters have said maybe a word with the handler.  Ultimately, judging and showing is for breeding purposes as such behaviour has to play some part as it's no good having the best sire in the world conformationally if it has a screw loose and can't behave for more than a milisecond at a time.  It's not just conformation that gets passed on in the genes.  So personally if my dog was maybe just a bit nicer than the next best dog who behaved impeccably I would expect to lose out to the better behaved dog.  Equally if my impeccably behaved average looking dog was totally outshone by something a bit scatty but stunning I would expect to lose out to the stunner.

I have a 4 year old who is a total nutter in the ring she just loves life and people.  She has won BIS at the first breed club, because she had the spirit and happiness that the judge liked.  She had a 2nd at a champ show and I have to say that the write-up was quite funny, this was the show straight after her BIS win on the same day.  She was just mental at this show, sniffing the floor and enjoying life but she did for a mili second move beautifully.  The judges write up was something along the lines, a stunning girl with everything going for her but maybe her owner and she need to do some training!

In my view a dog should be judged on it's merits, not on it's showmanship.  As long as the dog can be assessed then that should be enough. 

Obviously if two dogs are very close in quality then showmanship may tip the scales.

Yes, my girl's still a nutter at 7! She got BOB and G2 at an open show at 5 years old and the judge commented how nice it was to see such exuberance at that age! They do sometimes make me look like I haven't got a clue, but I don't mind the enthusiasm. :-)

Something to be remembered also is that for many breeds Post Graduate is the first class that any exhibit can enter after age classes, so it can contain complete novices who had never been shown through those with successful puppy/Junior careers.

My first Elkhound bitch was shown at nearly two so started in Post Graduate when first shown.
