Why your dog’s behaviour changes as they grow

Many dog owners feel caught off guard when their well-behaved puppy suddenly seems to forget everything they’ve learned.

Recall becomes unreliable. Lead pulling increases. Focus disappears.

This stage is often referred to as adolescence — and it’s a completely normal part of development.

Understanding what’s happening during this phase can make it far less frustrating.

What is dog adolescence?

Adolescence typically begins anywhere from around 6 months and can last well into a dog’s second year, depending on the individual.

During this time, dogs are:

  • Developing independence

  • Becoming more aware of their environment

  • Testing boundaries

  • Experiencing hormonal changes

It’s not regression — it’s development.

Why behaviour seems to “get worse”

You may notice:

  • Ignoring cues they previously followed

  • Increased distraction on walks

  • More excitement around other dogs or people

  • Difficulty settling

This happens because the outside world becomes more interesting than before.

Your dog isn’t forgetting — they’re reprioritising.

Consistency becomes more important

Adolescence is where habits become stronger.

If behaviours like pulling or ignoring recall are repeated, they can become ingrained.

Clear, consistent expectations — alongside appropriate outlets for energy — are key during this stage.

Managing energy and stimulation

Adolescent dogs often have:

  • Higher energy

  • Lower impulse control

  • Increased curiosity

Balancing activity with rest, and avoiding constant overstimulation, can help dogs stay more regulated.

Stay patient and realistic

This phase can feel challenging, but it doesn’t last forever.

With the right approach, many dogs come out of adolescence calmer, more focused, and easier to manage.

Progress may feel slower — but it’s still progress.

You’re not alone

Many owners experience this shift and wonder what they’re doing wrong.

In reality, you’re likely seeing a normal stage of your dog’s development.

Support during this period can make a significant difference in long-term behaviour.
