Daphne beat me to it! I have never seen a judge get through 10 dogs and hour in utility. And then they have to figure scores, do awards etc. BUT.... if some dogs do not show it will go faster. So with 34 dogs I would plan on 3 1/2 hours. That gives you time to set up and exercise your dog and maybe browse a while.
