The leash or lead is used to connect the dog to the handler, lead the dog, as well as to control the dog in urban areas. Most communities have laws which prohibit dogs from running at large. They may be made of any material such as nylon, metal or leather. A six-foot length is commonly used for walking and in training classes, though leashes come in lengths both shorter and longer. A long line (also called a lunge line) can be 3 metres (ten feet) or more in length, and are often used to train the dog to come when called from a distance.
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.
