Happy is the only one I took to actual training classes, she was 11 weeks old and in a class full of adult dogs lol Happy graduated top in her class, BUT I did NOT follow the methods of the class, I went purly for socialization not that that was much good lol they had this stupid rule about dogs not being allowed anywhere near each other everytime Happy barked the instructer made me scruff Happy and yell "NO" in her ear. she was 11 weeks old for gods sakes! being the shy person that I am it was more like pick her up and say "no" lol only one class that I evert took with Happy was good, it was private. another one I took Happy too, would yell at her and grab her when she was obviously scared, and then ordered she be on a prong collar because she is such a bad dog we never came back to that one lol
