I think we were the only family who had in puppy school for over a year . Good luck.
Embarassingly, i took one of my labs to puppy school for 3 and a half years. Well worth it in the end. Think we were the first to be put in 'time out' too. Just way too exciting for her. I would take a ball and throw it to her for half an hour before class to wear her out, but sometimes the class was just too much. Think she has a touch of ADD.
