Before you begin dog obedience training, choose the best method for you and your dog. Training styles vary, but most trainers agree that dogs respond best to positive reinforcement, such as praise or treats. One common training variation, known as clicker training, includes the use of conditioned reinforcer. There are plenty of dog training books and websites where you can learn about training techniques and determine which best suits you and your dog. When planning out your training methods, don't forget about socialization.
A training class is not there to train your dog. Its purpose is to teach you to train your dog so you will need to be committed to train your dog for short sessions (5 minutes) several times a day rather than just simply turn up for classes! This little bit of training everyday will be repaid with a lifetime of living with a well behaved dog. You will also learn to avoid problems before they begin as well as receive help to overcome any that you already have with your dog.
