Three Perspectives on the Subcaudal Pit

1. Anatomical (Western Medicine):

The subcaudal pit (perineal and sacrococcygeal region) lies just above the tail base, at the junction of the skin, pelvic floor musculature, and spinal termination. This area contains nerve root exits from the sacral and caudal spinal cord segments—direct extensions of the CNS.

In dogs, this region holds the spinal cord's endpoints plus connections to peripheral autonomic nerves, including the vagal system.

➡️ It is a neurological center—not an excretory one.

➡️ It is anatomically and functionally separate from the anus.

2. Functional (Polyvagal Theory & Neuroethology)

This zone—especially the space between the tail base and coccyx—is a parasympathetic trigger point.

Trembling in the pit, secretion outputs, drainage through ears or eyes: all of these reflect autonomic regulation.

When this area releases, changes ripple through the brain, gut, or lungs:

Chicco releases gas, drinks, falls asleep, or stops trembling.

➡️ The brain and nervous system only "let go" once this zone releases.

3. Energetic Perspective (TCM & Wei Qi Concept)

In Traditional Chinese Medicine, the subcaudal pit is seen as the lower exit of the Wei Qi field—the body's outer defense system. It acts as a last-resort drainage point for pathogenic factors that can no longer be held internally.

Discharge from this zone signals the opening of the final gate, releasing internal heat, dampness, or toxins. It connects directly to the brain–spinal axis as a posterior outlet.

🉐 Stagnant Qi in the Wei Qi zone → reversed flow, need for diaphragmatic release 🉐

🔴 This drainage loop maps the release of internal pressure through subcaudal stimulation.

It signals trapped Qi—life force energy—that cannot circulate properly through the diaphragm, leading to autonomic overload, impaired breathing, ear irritation, and pelvic hypersensitivity.

➡️ In dogs, this presents as:

• trembling of the rear, sudden sitting or licking around the anus,
• irritability when touched at the tail base,
• body-twisting or swaying motions to release pressure from the back end.

This loop typically activates during Qi collapses—when the body is under stress but cannot discharge through the diaphragm. In these cases, the subcaudal pit acts as an emergency valve.

Major Drainage Loop #1 – Cough, Chest Pressure, Exhale, Elimination

🔻Chicco can push it through the diaphragm all the way up to the larynx.

When Wei Qi releases, a hard mass appears in the throat—ranging in size from a small lump to a palm-sized square—accompanied by a harsh sound, a kind of cough or expulsion.

But this isn't respiratory.

It's energetic.

👉 In the past, this was replaced by extended licking of the lips and nose, sometimes lasting minutes. Today, Chicco can clear it via a cough—a deep, tension-releasing exhale that resets the entire pathway.

This is drainage.

Not a symptom.

Not a disease.

Not pathology.

This is a system reset.

The dog does it all.

He only needs an anchor — a polyvagal one, not a Western protocol.

One day, we sat by the stove and simply said:

Let's try this—no pressure, just together.

And it started working.

Even if everyone pretends we don't exist. That it can't be true.

It is true. Earned by life.

And on the invoice it says: €0.00
