How Should I train my dog?
10 years ago the very common approach to dog training was the "Alpha" approach, also known as dominance training.  This approach focuses on building a pack structure in the home where the humans are seen as higher in the pecking order than the dogs in the home.  Examples include leading at all times (ie through doorways and walks), and only allowing your dog to eat after you’ve finished dinner and using training aids like a shock/vibration collar to enforce behaviors. 

In recent years, many experts have recommended a positive reinforcement based training approach.  Although there are a lot of nuances, at its core this method uses rewards to guide your dog towards desired behaviors. Positive reinforcement training typically means using a signal (like a word or a noise) combined with training treats, loved toys or verbal praise to reinforce good behaviors or actions. Other benefits include strengthening the relationship between owner and dog and building a happy training environment.
