Beyond the Bowl: Part 3 — Managing Energy Spikes and the "Zoomies"

We are back with Part 3 of our series with behavioral neuroscientist Dr. Pepe Hernandez.

In our last update, we talked about biological "bandwidth" and how gut comfort helps a dog focus. This week, we are looking at the exact chemicals behind those sudden post-meal energy spikes, frantic behavior, and the famous "zoomies."

Dopamine & Noradrenaline: The Chemistry of Arousal

By Dr. Pepe Hernandez, PhD, CPDT-KA

Here’s the thing: many owners think a dog running wild after a meal is just "happy." But from a neurological perspective, sudden, frantic bursts of energy are often a sign of chemical over-arousal, not just joy.

When a dog eats, their brain releases neurotransmitters to manage motivation, alertness, and stress. Two of the biggest players here are Dopamine and Noradrenaline.

Dopamine: The Motivation Molecule

Dopamine is all about anticipation, reward, and motivation. It’s the spark that makes a dog want to seek out food. However, when a diet is packed with high-starch carbohydrates and processed fillers, it causes rapid spikes in blood sugar.

These spikes trigger an artificial surge of dopamine. Instead of a steady, focused drive, the brain gets flooded. This translates into frantic, hyperactive behavior where the dog can no longer process commands or settle down.

Noradrenaline: The Alertness Accelerator

Noradrenaline modulates alertness, vigilance, and the body's stress response. It determines how "ready for action" your dog feels.

When a dog's system is constantly working to digest heavy, unnatural starches, the body perceives that internal strain as a low-level stressor. This keeps noradrenaline levels artificially high. The result? A dog that is easily startled, hyper-vigilant, and prone to sudden, explosive energy dumps because their nervous system is locked on "high alert."

Stable Fuel Equals Stable Behavior

So, what does this actually mean for your daily routine?

When we transition dogs to clean, species-appropriate raw nutrition, we remove the roller coaster of starch-induced sugar spikes. Pure, bioavailable proteins and fats are digested slowly and evenly. By providing a stable fuel source, we keep dopamine and noradrenaline at balanced, functional levels.

“A balanced brain requires a balanced fuel source. When you eliminate the chemical spikes caused by high-starch fillers, you eliminate the frantic behavior that goes with them.”
