đ When Sound Sparks Fear: Whatâs Happening in Your Dogâs Brain? đ§ đž
Hereâs a gorgeous boy who I worked with this week who had become very sound sensitive due to specific noises that had occurred when he wasnât expecting it, and had now extended his anxiety to many general sounds.
That sudden bang, beep, or buzz? Itâs not just âannoyingâ â for some dogs, itâs a full-blown neurological alarm.
Hereâs whatâs happening inside their brain when fear kicks in:
đ§ The Amygdala Takes Over
This almond-shaped part of the brain scans for danger 24/7. Loud, unpredictable sounds? Instant red flag. It shouts âTHREAT!â before your dog even knows whatâs happening.
đ¨ Fight, Flight, or Freeze
Once the amygdala sounds the alarm, the body floods with stress hormones like adrenaline and cortisol. Your dog might bolt, bark, tremble, or shut down â all survival strategies.
đ The Thinking Brain Goes Offline
The prefrontal cortex â the part that helps with learning and decision-making â gets sidelined. Thatâs why your dog canât âjust listenâ or âsnap out of itâ when scared. Theyâre not being stubborn â theyâre overwhelmed.
đĄ Repetition Builds Association
If scary sounds keep happening, the brain starts linking the environment with fear. Thatâs how noise sensitivity can spread â from crow scarers to car doors to clinking dishes.
But hereâs the good news:
đ§ââď¸ With desensitisation, counter-conditioning, and trust-building, we can help rewire those fear pathways. The brain is plastic â and progress is possible.
Your dog isnât broken. Theyâre just trying to survive in a world that sometimes feels too loud. Letâs help them feel safe again. đ
