yES AS Liana said points are deduct for over cammanding the dog. Also the judge has to determine if the dog is being disobedience as you lose points for that too.
My partner whistles all his commands and I remember a judge last year telling dave he will get points deducted for excessive whistling VBG Had to laugh as how would the judge know if the dog was being over commanded. or what the whistles meant.
See when i say stop is doesn't mean stop as in a sit, I never ask my dogs to sit, stand or lay down i want a stop that is all and when I say stop I really means pause. if I say "stop there" its a longer stop but i still expect the dog to move if the sheep were to take off. A working dog is no good if it sits or lays there waiting for another command while the sheep are tearing down the paddock.
As a judge it is my job to decide if the stop command or wait command is what we think it is or is the dog not taking any notice of the handler at all.
