Teach a dog to sit by guiding it into the sitting position, while saying the word "sit." Do this with a treat in view, and then give the treat once the dog is in the sitting position.Continue Reading
This gives your dog a verbal cue, and it should eventually learn what the cue means.
Don't let the dog take the treat until it is in the sitting position, but keep the treat where the dog can see and smell it.
As you say sit and hold the treat within sight, push your dog's rump toward the floor.
Once your dog is in the sitting position, offer the treat. Give the dog plenty of praise, scratch its head, or rub its belly.
When you feel confident that your dog understands the cues, try getting it to sit without using a treat. Hold your hand in front of its face as you did with the treat previously, and give the command. If the dog sits, you can offer it a treat from your pocket, or provide praise.
It typically requires a few practice tries before your dog understands what you want from it. Keep trying, and your pet should learn.
