What age can it start going to Puppy classes? I was at least wanting it to go the Puppy class during the summer and then after I train with it more (few months), by myself, I can move on to CGC. Then after the CGC I was going to take it on a 'trial' hike and see if it would listen to what I was doing or not, and if not, I would take it to the obedience class or get a professional trainer.
