It's also known as Bio Sensor training and is - in a short explanation - early neurological stimulation. One of our extended family from our last litter asked if we did this with the litter their dog's litter. We did.
There is an extensive and very interesting article on it at http://www.breedingbetterdogs.com/articles/early_neurological_stimulation_en.php
It is a fairly simple method and takes very little time to accomplish. Each exercise is 3-5 seconds once a day from day 3 - 16. The results are well documented and include:
- Improved cardio vascular performance (heart rate)
- Stronger heart beats
- Stronger adrenal glands
- More tolerance to stress
- Greater resistance to disease.
