I am new to judging, but I don't think all these things are discussed prior to an event but should be watched for by both judges. However, per the rulebook, judges should discuss in advance:Is it common for judges to come to an agreement on these sort of scenarios before an event?
examples might include
see the handler intimidate the dog
see the handler touch the dog
hear verbal before released and after birds were called for
see handler pinch lip for a sticky mouth or step on toe
and if one judge is watching the honor dog/handler and the other is watching the birds thrown/working dog...
1 - instructions to handlers
2 - who signals for birds
3 - who calls the dogs number
4 - each judge has liberty to say "no bird"
5 - every bird retrieved should be inspected (preferably by the judge not calling numbers)
6 - who gives instructions to handler if dog is to be picked up
7 - running or crippled birds - judges should decide in advanced how to deal with runners should problem arise
8 - judges should decide how to deal with encountering of wild birds
9 - agree in advance on creeping and if dog should be brought to heel before sending. (also in minor stakes, judges should agree about the degree of controlled break)
