I begin using a little bat or whatever as a cue stick and then just using my index fingers, teach to move the hindquarters away from pressure, first tapping the air and using body language while looking strong at the hindquarter, then lightly tapping the hip until they take a step. Then rub it to reward and change the body language by standing and telling them how good they did. It doesn't take long if they are used to any ground lessons at all. Next wait until they cross over before releasing pressure and rubbing. Then do the opposite side. Then teach using the same method for the forequarters pressuring the shoulder instead of the hip, and expecting them to cross over the front feet, both sides. This is also wonderful exercise for their chest and hiney. They pick it up real quick until just your finger signaling cues, I also kiss because it is easy and handy and my guys know kissing means some sort of movement, my body language or fingers signals them what to move.
Then the easy part is to stand them in front of a wall, fence, whatever and point to the shoulder then the hip, and back and forth with your finger and they move beautifully to the side. Always start with one step, then two and so on. reward the slightest try in the right direction. I have taught it so many times now that I can teach the whole process in one day. I hope I wasn't too confusing. Becky
