Well my dog is almost 3 and I was wondering if I can still put him in an obedience class. He knows the basic stuff-sit, lay down, shake, shake with the other hand, roll over, stay, fetch, come. He just needs to be more obedient doing them. I understand he's part Jack Russell and being obedient isn't their thing but there has to be a way to show him I'm the boss. Would going to an obedience class help? Would he be considered to old since he's not a puppy anymore? Would I be to far ahead of the class? He is really smart and knows what I mean but if he decides he has something else to do he's going to do it instead of come, sit, lay down, rollover, etc.
