Teaching the “Sit” command; alternate method
NOTE: this is an alternate method, which I recommend only when the primary method has failed or is unsuitable for some reason.
Grip the dog?s leash about 8-10? from the collar with your right hand. Position your other hand on the dog?s back, just above the tail. Call the dog?s name to get his attention, then give a single command to sit in a clear, pleasant tone of voice. After instructing the dog to sit, pull firmly upwards on the collar while pushing down on his rump with your left hand.
Once the dog is in a sitting position, release pressure on his collar while keeping your hand on his rump to encourage him to remain seated. Quietly pet and praise the dog, taking care to avoid exciting him into standing up again. After a few moments, say ?Okay? in a clear, cheerful tone of voice and release the dog.
Repeat this exercise. Over time, you will find it becomes easier to mold the dog into the sit, using only a slight tug on the lead and a gentle touch on the rump. Watch for signs that the dog has figured out how to sit without assistance.
The first time he sits without physical help, praise him effusively and end the training session. You want him to remember how delighted you were when he sat on his own!
When the dog begins sitting on his own part of the time, encourage this behavior by praising excitedly. When the dog requires assistance to sit, give minimal praise, thus making it clear to the dog which behavior you refer. Practice consistently, your goal being to get to the point where the dog never needs ?reminding? to sit.
