Arizona does not change clocks.
Our dogs still experience fall.
The sun goes down earlier.
Temperatures become more comfortable.
Evening walks move into darkness.
Families shift when they spend time outside.
Holiday routines begin.
Puppies continue developing.
Adolescent dogs change.
Adult dogs suddenly have more usable outdoor time after summer.
Senior dogs may sleep more.
As a behavior trainer and veterinary technician, I do not look at all of this as one problem called “the time change.”
I ask three questions:
What can we prevent?
What behavior needs to be taught or modified?
What does this dog need for recovery?
The Three Parts of Behavior Support
Prevention
Prevention means changing the environment before the dog struggles.
Examples include:
- Moving puppy activity into safe lighted periods.
- Adding indoor enrichment when evening walks get shorter.
- Using reflective walking equipment before darkness becomes a problem.
- Protecting puppy naps.
- Maintaining predictable bathroom opportunities.
- Supporting senior-dog traction and mobility.
- Keeping medication and feeding routines dependable.
Behavior Modification
Behavior modification changes what the dog learns or how the dog responds.
Examples include:
- Helping a dog become comfortable walking after dark.
- Teaching flexibility around meal timing.
- Counterconditioning a dog worried by nighttime people, shadows or wildlife.
- Teaching an adolescent dog to disengage from distractions.
- Building settling skills during evening activity periods.
Recovery
Recovery means looking at what happens afterward.
- Can the puppy nap?
- Can the adolescent settle?
- Can the adult dog return to baseline after the walk?
- Can the senior dog rest comfortably?
Recovery tells us whether the activity matched what the dog was ready for.
Dogs Follow Patterns More Than Human Clock Numbers
Your dog does not need to understand 5:30 PM.
They know what predicts dinner.
- You come home.
- Shoes come off.
- The kitchen becomes active.
- Another pet is fed.
- The light outside changes.
- The household begins settling.
Dogs learn patterns.
That is why seasonal changes affect Arizona dogs even though most of the state does not change clocks.
Emerging Puppy Research Is Changing the Daily Schedule Conversation
One of the most interesting current developments in puppy research comes from Duke Puppy Kindergarten.
Activity-monitor data collected from young puppies approximately 8 to 20 weeks old has been reported as showing four average periods of increased daily activity.
This is emerging researcher-reported data.
It should not become a rigid rule requiring every puppy to play exactly four times per day.
It gives us a better framework for understanding why young puppies may have multiple predictable periods when they become naturally more active.
Use Activity Windows, Not Exercise Quotas
A puppy activity window might include:
- Potty.
- Food.
- Short training.
- Sniffing.
- Exploration.
- Socialization.
- Play.
- Handling practice.
Then:
Rest.
The goal is not to exhaust the puppy.
The goal is to meet developmental needs while the puppy is awake and protect sleep afterward.
People Call It “Puppy Energy.” What Are We Actually Seeing?
Clients often say:
- “My puppy is crazy.”
- “He has too much energy.”
- “She is being bad.”
- “He needs to run it out.”
Those descriptions do not explain the behavior.
The puppy may be experiencing:
- A natural activity peak.
- Overtiredness.
- Overarousal.
- Frustration.
- A need to eliminate.
- A need for interaction.
- Insufficient enrichment.
- Too much stimulation.
- A developmentally normal burst of activity.
Different causes require different responses.
The Evening “Witching Hour”
Many puppy owners recognize the pattern.
The puppy begins:
- Zooming.
- Biting.
- Grabbing clothing.
- Jumping.
- Stealing objects.
- Playing frantically.
- Ignoring cues they performed earlier.
- Struggling to settle.
It is tempting to conclude:
“My puppy needs more exercise.”
Sometimes the opposite is true.
Look at:
- How long the puppy has been awake.
- How much stimulation occurred.
- Whether they need to eliminate.
- Whether they have slept enough.
- Whether this is one of their naturally active periods.
- What happened immediately before the behavior.
Shorter Days Change Where Puppy Activity Happens
A puppy’s developmental rhythm does not disappear because the sun sets earlier.
An evening activity period that happened outside in September may happen after dark in November.
Now the environment needs to change.
Options include:
- Short lighted walks.
- Sniffing.
- Search games.
- Training.
- Interactive feeding.
- Puzzle activities.
- Body-awareness work.
- Handling practice.
- Indoor play.
- Short outdoor exploration in a safe lighted area.

Development Changes the Dog Too
Young Puppies
Expect:
- Frequent activity-rest cycles.
- Frequent elimination needs.
- Short learning sessions.
- Exploration.
- Large sleep needs.
- Rapid development.
Adolescent Dogs
Clients often say:
“My dog forgot everything.”
A more useful description is:
“My adolescent dog responds differently in this environment.”
Adolescence may bring:
- More independence.
- Greater environmental interest.
- Changing social behavior.
- Changes in impulse control.
- New sensitivities.
- Developmental fear periods.
The training may still exist.
The conditions changed.
Adult Dogs
Adult routines are generally more stable.
Arizona fall often increases outdoor opportunities after summer heat.
Increase physical activity progressively.
A dog who spent summer doing short early-morning walks is not automatically conditioned for a long hike because the weather improved.
Senior Dogs
People often say:
“He is slowing down.”
That observation deserves more detail.
Older dogs often rest more.
We still need to ask:
- Is this normal for this dog?
- Can they rise easily?
- Are they comfortable?
- Do they still enjoy normal activities?
- How are appetite and drinking?
- How is nighttime sleep?
- How is mobility?
- How is cognition?
Senior Dog Sleeping More: Seasonal or Something More?
Extra rest is more reassuring when your senior dog:
- Wakes normally.
- Still enjoys favorite activities.
- Maintains appetite.
- Drinks normally.
- Moves comfortably.
- Uses the bathroom normally.
- Remains socially engaged.
- Sleeps more after increased activity.
- Still engages when awake.
A new change deserves closer attention when it occurs with:
- Difficulty waking.
- Reluctance to rise.
- Stiffness.
- Limping.
- Reduced interest.
- Weight change.
- Appetite change.
- Increased thirst.
- Urination changes.
- House-soiling.
- Panting.
- Nighttime pacing.
- Nighttime wakefulness.
- Disorientation.
- Getting stuck.
- New anxiety.
- Vocalization.
- Weakness.
Client Language: “He Is Just Getting Old”
Age matters.
Age should not explain every new behavior automatically.
Instead of:
“He is just getting old.”
Try:
“My 12-year-old dog began sleeping several more hours during the day, hesitates before standing and started pacing at night.”
That gives a veterinary professional useful information.
If you are unsure whether the change reflects routine, age, pain, illness, medication effects or cognitive change:
Earlier Darkness Changes Adult-Dog Behavior Too
Your normal walk may look different after sunset.
Dogs experience:
- Different shadows.
- Different movement.
- Wildlife.
- People appearing with less warning.
- Headlights.
- Bicycles.
- Dogs that are harder to see from a distance.
A dog who seems “more reactive at night” may be responding to a changed environment.
Instead of:
“My dog is reactive at night.”
Try:
“My dog begins scanning and barking when people appear suddenly from darker areas.”
That gives us something useful to modify.
Prevention for Shorter Days
- Move difficult walks into daylight when practical.
- Use familiar routes after dark.
- Use secure walking equipment.
- Add reflective or illuminated equipment.
- Give puppies appropriate active opportunities earlier.
- Protect nap times.
- Maintain bathroom opportunities.
- Support senior-dog traction.
- Plan indoor enrichment before darkness removes an outdoor option.

Behavior Modification for the New Routine
Reduce difficulty when the environment changes.
For walking after dark:
- Start with a short familiar route.
- Choose a quieter period.
- Allow sniffing.
- Create distance from triggers.
- Reward check-ins.
- Return before the dog becomes overwhelmed.
- Build gradually.
For schedule changes:
- Shift gradually when practical.
- Keep predictable routine anchors.
- Practice small variations so the dog develops flexibility.
For puppy evenings:
Alternate activity with rest instead of extending stimulation indefinitely.
Recovery: Protect the Downshift
People focus heavily on activity.
I want you watching what happens after activity too.
- Can your puppy nap?
- Can the adolescent settle?
- Can your adult dog recover after the walk?
- Can your senior dog rest comfortably?
A dog who finishes an activity and remains restless, panting, scanning or unable to settle is giving you information.
The activity may have exceeded what they were ready for that day.
What if Your Dog Is “Lazy” in Fall?
“Lazy” is not a behavior diagnosis.
Describe what changed.
- Sleeping longer.
- Moving more slowly.
- Refusing walks.
- Taking longer to stand.
- Losing interest in play.
Those observations lead to better decisions.
Sometimes the reason is seasonal routine.
Sometimes it is increased exercise followed by normal recovery.
Sometimes it is developmental.
Sometimes it is medical.
If you are unsure:
Food and Probiotics
Do not automatically reduce food because daylight becomes shorter.
Arizona dogs often become more active when temperatures improve.
Nutrition should reflect:
- Growth.
- Life stage.
- Body condition.
- Actual activity.
- Health.
- Training demands.
- Veterinary needs.

When Tips Are Enough
Start with routine adjustments when:
- The behavior is mild.
- Your dog recovers normally.
- The change clearly follows a routine shift.
- Your dog remains physically well.
- You can manage the environment safely.
When to Get More Help
Seek more support when:
- The dog cannot recover.
- Fear increases.
- Reactivity becomes harder to manage.
- The puppy cannot settle despite adequate sleep opportunities.
- The dog repeatedly refuses normal activities.
- House-soiling begins.
- The schedule change exposes an existing behavior problem.
- You do not know which training pathway fits.

Frequently Asked Questions
Do Puppies Really Have Four Daily Activity Peaks?
Emerging Duke Puppy Kindergarten activity-monitor findings suggest young puppies show four average daily activity peaks.
This is useful emerging evidence, not a rule requiring four exact play sessions.
Does My Puppy Need More Exercise During the Evening Witching Hour?
Not automatically.
Evening hyperactivity may reflect a natural active period, overtiredness, overarousal, elimination needs or accumulated stimulation.
Review the entire day before adding more exercise.
Did My Adolescent Dog Forget Their Training?
Usually, “forgot training” is not the most useful description.
Adolescence changes motivation, environmental interest and responsiveness.
Describe where the behavior changes and under what conditions.
Is My Senior Dog Just Getting Old?
Age changes sleep and activity.
New mobility, appetite, cognition, elimination or nighttime changes deserve further evaluation.
