at the end of the day if i was judgeing i would be looking at;- good conformation, good free movement ,good condition;- not too fat/thin/ good coat condition, fit for purpose, correct scissor bite, balanced temperament (not aggressive or too nervous), personally it wouldnt matter to me if a dog is marked or not, colour and markings.if it is male that both testicles are decended (apart from pups)
when you judge dogs you judge each animal individually, if its possible to follow a breed standard then you do so, in the case of working dogs you cant always do that.
