When people talk about 'obedience training' are they referring to actual classes and trainers or just basic obedience, like teaching to 'sit', 'stay', 'no', 'heel'...etc that can taught at home? Taking obedience training classes, I would think would be expensive. My Dixie, although stubborn, has been pretty easy to train with basic commands. My new energetic 8wk old Australian Shepherd on the other hand? May take a bit more training.
