Understanding ENS and ESI for Newborn Puppies and WHY I do this!

Welcoming newborn puppies into the world is an exciting time, filled with joy and new responsibilities. While their adorable faces and tiny paws steal my heart, it’s crucial to remember that the first weeks of life are vital for their physical and behavioral development. Two techniques that I use are Early Neurological Stimulation (ENS) and Early Scent Introduction (ESI). These techniques can set your puppies on a path toward a healthier and more confident adulthood.

Let’s dive into what ENS and ESI are, their benefits, and how I implement them into all of my puppies lives.

ENS is a series of simple, controlled exercises performed on puppies between the ages of 3 and 16 days. These exercises were initially developed by the U.S. military for their “Bio Sensor” program, aiming to improve the overall performance of working dogs. ENS involves five specific activities that expose puppies to mild stressors, stimulating their neurological systems and boosting their development.

The Five ENS Exercises:

  1. Tactile stimulation: Gently rub a cotton swab between the puppy’s toes.
  2. Head held erect: Hold the puppy upright, perpendicular to the ground.
  3. Head pointed down: Gently turn the puppy so its head points toward the ground.
  4. Supine position: Hold the puppy on its back, ensuring it’s calm and secure.
  5. Thermal stimulation: Place the puppy on a cold, damp towel/ice pack for a brief moment.

Each exercise should last about 3-5 seconds, and should be repeated daily. I also try my best to keep it at the same time of day for structure and consistency.

ENS exposes puppies to mild stress, which helps them build resilience and adaptability. Studies show it offers several long-term benefits:

  • Improved cardiovascular performance: ENS supports a healthier heart.
  • Stronger immune system: Puppies tend to resist illnesses more effectively.
  • Greater stress tolerance: They handle new environments and situations with less fear.
  • Enhanced problem-solving abilities: ENS contributes to sharper mental acuity.

Early Scent Introduction is another technique that complements ENS. Puppies are introduced to a variety of scents between 3 and 16 days of age. This period, often referred to as the “neonatal phase,” is when their brains are highly malleable. By exposing them to different scents, we can enhance their ability to recognize and process smells later in life.

How to Perform ESI:

  • Present a single, distinct scent to the puppy for about 5-10 seconds.
  • Use a variety of safe items such as lavender, leather, banana, or feathers.
  • Allow the puppy to sniff and engage with the scent at their own pace.
  • Repeat daily with a new scent.

The olfactory system is one of the most developed senses in newborn puppies. ESI takes advantage of this and provides benefits such as:

  • Enhanced scent discrimination: Puppies grow up with better scent recognition skills, which is especially beneficial for working or service dogs.
  • Increased confidence: Familiarity with a variety of smells can reduce fear responses to new environments.
  • Stronger bond with humans: Puppies may associate positive experiences with their handlers through scent interaction.

When I introduce ENS and ESI to newborn puppies, I keep these things in mind:

  1. Gentle Handling: I am always gentle and calm to avoid overwhelming the puppies.
  2. Consistency: I perform the exercises daily during the critical 3-16 day window.
  3. Hygiene: I always wash my my hands and any tools used to prevent infections.
  4. Monitor Reactions: I pay close attention to each puppy’s comfort level. If a puppy seems overly stressed, I stop and try again later.
  5. Record Keeping: I record all ENS and ESI results for each puppy and forward these records to their forever families.

ENS and ESI are simple yet impactful practices that can help your puppies grow into healthier, more adaptable dogs. By dedicating just a few minutes each day during their neonatal phase, I give them a strong foundation for both physical and mental well-being. These techniques are well worth incorporating into the care and routine of your new puppy.

Remember, a confident and resilient dog begins with intentional care in the earliest days. Your furry friends will thank you with wagging tails and boundless affection for years to come!
