If you get into dog training make sure it is in accordance with your training style. There are several methods available. Such as clicker training, positive reinforcement(reward for desired behavior), collar training (correction for unwanted behavior), etc...

Most dog clubs now do positive training. There are several good books on the market about training. If you are not sure what style you prefer they may help guide you. Once you determine this find a dog training club in your area that adheres to your style. Volunteer when possible. Ask if you can work with the main instructor. There are AKC classes held for instructional and testing trainers.

The best way to get into training though is work with your own dog and just get involved in a local club.
