The word "No" The word no is an important one for your dog to learn, and one you may be using a lot as training begins. It is important that the dog learn to respond to a sharp "No" promptly and obediently.
The "Sit" command The sit command is another vital link in the chain that is dog training.
Teaching a dog to sit on command, using voice commands alone, will form the groundwork of much future training, so it is important for the dog to master this vital skill.
The sit command can be combined with the heel command. As you walk alongside your dog, stop abruptly. If your dog does not stop when you do, give a sharp tug on the leash to remind the dog. Many dogs will instinctively stop when you do, while others need to be reminded through the use of the leash and the training collar.
Once the dog has stopped by your side, urge him to sit by pushing gently on his hindquarters. It is important not to use too much pressure, or to push him down abruptly. Doing so could frighten, or even injure the dog. Rather, apply a steady downward pressure. Most dogs will recognize this as a sit command. It is important to say the word sit as you do this.
Repeat this procedure a few times by walking, stopping and sitting your dog. After a few repetitions, the dog will probably begin to sit down on his own every time he stops. It is important to say the word sit each time, so that the dog will eventually learn to respond to voice commands alone.
The "Stay" command
Like the sit command, the stay command is a vital building block to other, more advanced training. For instance, the stay command is vital to teaching the dog to come when called, which is in turn vital to off leash work.
The stay command can be made into an extension of the sit command. Have your dog sit, and while he is sitting, slowly back away. If the dog begins to follow you, as he probably will it first, come back to the dog and ask him to sit again. Repeat the process until you can reach the end of the leash without your dog getting up from a sitting position.
After the dog is reliably staying where you indicate, you can try dropping the leash and backing further away. It will probably take the dog some time to reliably stay where he is put without becoming distracted.
