How old is this dog?
And how was this exercise taught?
What do you do when your dog FINALLY responds? Reward? what and how?
I don't stand around and wait for the dog to respond. Dog hears the command, and there should be a response. If not, then "assist", where the assist is determined by the basic temperament of the dog and how well your dog understands the command. This is definitely NOT a one size fits all situation.
The dog should be in drive FIRST.....but that's no excuse for not complying.
