Adolescence typically runs from about 6 months to 2 years, but it varies based on breed, size, and individual temperament. (It can start as early as 5 months and last up to four years.)

Your adorable puppy might suddenly seem like a completely different dog. They’re learning to manage emotions, navigate social situations, and figure out what matters in their world.

As your puppy grows, their brain doesn’t develop in a straight line. It moves in waves. Your dog isn’t regressing or “becoming fearful.” They’re learning how to evaluate the world more carefully.

One day:

“That’s interesting!”

Next day:

“Wait… is that safe?”

✔ This is normal
✔ This is expected
✔ This is part of learning how to think, not just react

The Phases

Early Puppyhood
Everything is interestin, curious chaos navigator.

Adolescence
Testing boundariesm moody & lots of energy

Adulthood
Been there, done that. I’ve got it.

What You Might Notice

During these developmental waves, dogs often:

Hesitate around things they used to ignore

Bark or pull away from people, places, or things that they previously had no issue with

Approach more slowly or avoid entirely

Have good days… followed by “what just happened?” days

That inconsistency is your biggest clue that this is a phase, not a training failure. During adolescense this often shows up in 1–3 week waves and can continue on and off into early adulthood

Risk-Taking, Arousal, & Impulsivity

The adolescent brain hits the gas on fun and exploration, but the brakes (self-control) haven’t fully developed.

This mismatch can lead to:

More impulsivity and erratic behavior

“Regression” in previously solid skills

Stronger reactions to movement or noise

Adolescent dogs aren’t trying to be difficult. They’re having a difficult time.

Try This

Revisit enrichment and add breed-specific outlets

Scale back outings when overstimulated

Do more at-home work

Add low-key outings like sniffaris away from your neighborhood in quiet, empty parking lots on the weekend, a hike with a calm friend, or backyard games (fetch, flirt pole)

Social Shifts

Teenage dogs often get more selective. Watch for:

Avoidance or tension with certain dogs or strangers

Stiff greetings, mounting, or posturing

Increased barking or unease in play

Tips:

Reduce exposure to unfamiliar dogs for now

Take a break from large daycare groups and dog parks

Choose calm, known social partners

Use parallel walks or solo play

If possible, opt for a trusted walker or small, structured care

Decreased Responsiveness

Yesterday they sat on cue. Today they zoom off. That’s normal.

Try this:

Practice known skills in new places

Teach new skills in familiar environments

Use simple pattern games (Name Game, Up & Down, “1-2-3”)

Rotate rewards to keep motivation high

Offer more choice when things feel hard (mat work helps)

Emotional Regulation

Adolescents don’t handle delays or surprises well yet.

This can look like:

Whining, barking, or mouthing when frustrated

Losing interest in favorite activities

Meltdowns when things take too long

Keep in mind that emotional regulation is still very much a work in progress. Think of it like getting cut off in traffic. That stress spike is instant. When you get a chance to pull over to collect yourself, things calm down, and you can get back to thinking clearly. Our adolescent dogs need those same “pull over” moments. Without enough of them built into the process, the behaviors we’re trying to build will take much longer to take hold.

Training Ideas for Better Regulation

Build Stay Duration

Teach your dog to go to a spot and wait while you prepare food.

Start with short, easy waits

Gradually increase duration

Release with a consistent cue

Goal: Build patience during high-energy moments

Practice Manners

Use mats and interior doors

Reinforce staying while you move first

Increase difficulty weekly, not daily

Add “send away” to a mat across the room

⏱ Just 10 minutes, twice a day, for 3 weeks builds focus, patience, and resilience.

Remember This

Your dog is watching how you handle the hard moments. Your tone, timing, and patience teach them how to:

Settle

Think

Trust

Predictability creates security.
