Here are some basic and useful commands worth teaching your dog.
Sit, Stay, and Come - The norm.
Heel - Positions the dog at the trainer's left side, or alternately between his legs facing forward when at rest.
Settle - Settle down. Down - Get down or lay down, depending on the circumstances.
Show - Stand at full height on hands & toes, legs spread, all parts accessible and on display.
Eyes up, looking forward.
In addition to the above, the human dog can be issued somewhat more complex commands once it has been properly conditioned to respond to its trainer. Being slightly more intelligent than other breeds, a well trained dog is capable of understanding things like "Go fetch my boots" or "Beg for it, bitch". Other commands can be added or the above modified to suit the handler's needs, but all commands that will be used regularly should be properly reinforced during regular training sessions for maximum effectiveness.
