I have taken two, and I have observed as well.
The first lady was good. She did encourage me to go to shows with my dogs and had done so. That was an ok experience.
The boy in the next class was terrible. He was just totally inexperienced and had no clue.
I saw one of the trainers trying to get the owners to use a treat bag with one hand and a jar of pennies with the other, and somewhere there was a clicker, and I was like, wow! The puppy and I were on the same page, completely confused.
But my last visit to Petsmart, there was an advanced class working near the door. they were doing a game where each had their dog do a behavior, then another member added a behavior and each class member did both behaviors, and they kept on going. It was something like SIT, DOWN, STAY, RECALL, SIT, TWO DOGGIE PUSH UPS, PUT A TREAT ON THE PAW, LEAVE IT. It was actually pretty impressive for them to have gotten to that point with PetsMart training.
So, it really does depend on the instructor. Some are good, some are not so good.
