By far the most important early training for any puppy is socialization to other puppies and dogs, to people and to everything else they will ever encounter in their lives. This is also the ideal period for a puppy to “learn to learn” and that command compliance might earn a reward.
A positive interrupter is a way of redirecting your dog’s attention from an unwanted activity back to you so that you can then cue an activity that you’d rather he be doing, such coming to you, sitting, laying down or staying.
Reward-based training is the scientifically proven method for teaching dogs desirable behaviors. Treats are your dog’s paycheck, not a bribe, and having her “work” sets you both up for years of fun, exciting interspecies communication.
The domestic puppy’s unique and unusual capacity for socialization to multiple species allows us to insert ourselves into their social milieu and to substitute ourselves into a role that would otherwise be served by their parents.
Fear is a natural response that serves a useful purpose: Avoiding rather than engaging an unfamiliar stimulus might save your life. Desensitization and counter-condition is a way to help your puppy to become more comfortable with strangers, garbage trucks or whatever frightens them.
