How do you train a Shetland Sheepdog to sit?

Answer 1

The same way you train any dog. Push down on its butt and force it to sit while simultaneouly saying, "Sit." Then give it a treat (I use bacon). Do this over and over until the dog does it without your pushing. Give treats often.

Answer 2

Place one hand on their rear end and push lightly down to make them sit, but make sure their chest doesnt go down, and say 'sit' over and over, they will learn this quickly.
