At what age would you start using a clicker with a pup? And what age would you start serious obedience? I figure you'd want to start right away (9 1/2 wekks) with basic stuff like potty training and not chewing on things, but at what age would you start with the hard stuff like recalls and such? Is this something you gradually want to get the pup into, or is it important to start training at day 1? I know everyone says a bored puppy is a destructive puppy, which I no reason to refute, but should they be allowed time to be a puppy?
