Early Neurological Stimulation (ENS) exercises, which are conducted once daily from the third to the 16th days, a period believed to be a time of rapid neurological growth and development. Even though puppies are very immature during this time frame, they are sensitive and respond to ENS. The US Military developed this method designed to improve the performance of future military working dogs, according to the Breeding Better Dogs program developed by Dr. Carmen Battaglia, esteemed breeder, judge, seminar presenter, and AKC board member. ENS requires handling the puppies one at a time while performing a series of five exercises. Listed in order of preference, the handler starts with one pup and stimulates it using each of the five exercises. The handler completes the series from beginning to end before starting with the next pup. The handling of each pup onceper day involves the following exercises:
1. Tactile stimulation – Holding the pup in one hand, the handler gently stimulates (tickles) the pup between the toes on any one foot using a Q-tip. It is not necessary to see that the pup is feeling the tickle. Time of stimulation 3 – 5 seconds.
2. Head held erect – Using both hands, the pup is held perpendicular to the ground, (straight up), so that its head is directly above its tail. This is an upwards position. Time of stimulation 3 – 5 seconds.
3. Head pointed down – Holding the pup firmly with both hands the head is reversed and is pointed downward so that it is pointing towards the ground. Time of stimulation 3 – 5 seconds.
4. Supine position – Hold the pup so that its back is resting in the palm of both hands with its muzzle facing the ceiling. The pup while on its back is allowed to sleep. Time of stimulation 3-5 seconds.
5. Thermal stimulation— Use a damp towel that has been cooled in a refrigerator for at least five minutes. Place the pup on the towel, feet down. Do not restrain it from moving. Time of stimulation 3-5 seconds.
