✨ENS started Day 3✨
ENS stands for Early Neurological Stimulation. It is a series of five quick, gentle exercises performed on newborn puppies between days 3 and 16 of their lives. Originally developed by the U.S. Military, the program is designed to stimulate the neurological system and improve an animal's resilience and stress responses as an adult.
Each exercise is performed just once a day, for 3 to 5 seconds per exercise:
1. Tactile Stimulation: A Q-tip or your finger is used to gently tickle the puppy between the toes on their feet.
2. Head Held Erect: The puppy is held vertically, with its head pointing straight up.
3. Head Pointed Down: The puppy is held vertically, but the head is reversed to point down toward the ground.
4. Supine Position: The puppy is held flat in the palm of the handler’s hand with its muzzle pointing toward the ceiling.
5. Thermal Stimulation: The puppy is placed (feet down) on a damp towel that has been chilled in the refrigerator for at least 5 minutes.
When done correctly, proponents of ENS suggest it yields lifelong benefits, including:
Stronger cardiovascular performance: Improved heart rates and stronger heartbeats.
Better stress tolerance: A healthier fight-or-flight response that helps dogs stay calm and adapt to stressful situations.
Stronger immune systems: Enhanced resistance to disease.
Improved problem-solving: Puppies often grow into more active and exploratory learners.
It is important to note that ENS is not a replacement for puppy socialization. ENS focuses strictly on neurological and physical development during a highly sensitive window, whereas socialization (which begins around 3 weeks of age) focuses on safely exposing the puppy to the outside world, different textures, sights, and people.
