When we train or live with dogs, we often focus on behaviour; but behind every behaviour are ✨chemicals✨ Two of the most powerful elements are dopamine and serotonin… both I like to talk about often!
In a short - They shape how your dog feels, learns and connects with you. So? What are they?…
💥 Dopamine: The Drive Chemical
Dopamine fuels motivation, focus and desire.
It’s released when your dog anticipates something rewarding, not just when they get it.
That’s why the moments of “hope” ( which anyone who trains with me will know) before the ball ( or reward is given) or before the marker word is said are so powerful.
✅ Dopamine supports:
• Engagement and enthusiasm
• Goal-directed behaviour
• Learning through prediction (“If I do this, good things happen!”)
But… with that being said too much dopamine without structure can tip into frustration or over-arousal. Think of the dog that barks with excitement waiting for the ball to be thrown or pawing you ‘nagging’ for the treat.

🌿 Serotonin: The Stability Chemical
Serotonin is about contentment and safety.
It helps your dog feel calm, resilient and emotionally stable.
This is the neurochemical foundation for trust and self-regulation.
✅ Serotonin supports:
• Calm confidence
• Impulse control
• Emotional recovery after stress
Low serotonin = anxious, reactive, or easily frustrated behaviour.
Building serotonin takes consistent safety, predictability, and rest.
⚖️ The Balance
Healthy training and relationship-building aim to balance the two:
• Dopamine drives curiosity and motivation.
• Serotonin anchors the dog in safety and stability.
When you create training that’s exciting and emotionally safe, you get a dog who wants to work with you — not one who has to.
💡 For those looking to delve deeper into your training try this:
After an energetic play or training session (dopamine), take a slow sniffy walk or relaxed settle together (serotonin).
You’re helping your dog’s brain find balance — and that’s where real partnership lives. Happy training 🐾✨
