Typically between 6-18 months (can vary by breed), this is when your sweet puppy suddenly seems to "forget everything."
Listening? Gone.
Recall? Questionable.
Attitude? Peak chaos.
It's not disobedience - it's biology.
During adolescence, your dog's brain is undergoing a major remodel.
The prefrontal cortex (decision-making and impulse control) is still developing, while the emotional centre is in overdrive.
Hormones are running the show. Just like in human teens, there is increased testosterone / estrogen, heightened arousal and reactivity, and greater interest in the environment.
This = more impulsive, distracted
behaviour.
It's a "risk-taking" phase.
Adolescent dogs are wired to explore more, push boundaries, and take risks.
From a survival perspective, this helps them become independent.
But in modern life? It looks like chaos.
Your dog hasn't forgotten their training.
Their brain just can't access it reliably under distraction yet.
Impulse control is still under construction.
There is increased sensitivity & fear periods!
This is linked to changes in the brain's emotional processing systems.
Your dog's brain is more sensitive to dopamine (reward chemical).
New smells > you
Other dogs › you
Literally anything exciting › you
They're not choosing to ignore you, you're competing with biology.
Why this phase is so tough on owners:
• Expectations vs reality clash
• Frustration builds
• It feels like you're going backwards
This is the stage where many dogs are unfortunately given up.
What your dog actually needs from you:
• Consistency over perfection
• Patience over punishment
• Guidance, not pressure
They're not giving you a hard time...They're having a hard time.
This phase doesn't last forever.
With the right support, your chaotic teen becomes a stable adult.
