When Your Pet’s Sleep Patterns Change (And Why It Matters More Than You Think)

Most pet parents notice changes in eating or movement.
Far fewer notice changes in sleep.

But sleep patterns are one of the clearest windows into a pet’s physical comfort, emotional state, and overall health. When sleep changes, it’s often one of the earliest indicators that something deeper is happening.

What “Normal” Sleep Really Looks Like for Pets

Dogs and cats sleep more than humans, but not randomly.

  • Dogs: typically 12–14 hours per day (more for puppies and seniors)

  • Cats: often 12–16 hours per day, with short bursts of activity

Healthy sleep is:

  • Predictable

  • Relaxed

  • Easy to transition in and out of

  • Free of restlessness or constant repositioning

When those qualities change, it’s worth paying attention.

Sleeping More Isn’t Always Just “Being Lazy”

An increase in sleep can look harmless, but context matters.

Watch for:

  • Sleeping through normally engaging activities

  • Skipping greetings or routines

  • Difficulty waking or sluggish transitions

  • Choosing isolation over shared resting spaces

Excessive sleep can be linked to:

  • Pain or discomfort

  • Illness or inflammation

  • Emotional stress

  • Depression-like states

  • Age-related cognitive changes

The key question isn’t how much they sleep, but what they’re missing while sleeping.

Sleeping Less Is Often a Red Flag

Decreased sleep or restless sleep is easier to miss, but often more concerning.

Signs include:

  • Pacing at night

  • Frequent position changes

  • Difficulty settling

  • Nighttime vocalization

  • Increased nighttime alertness

This can point to:

  • Pain (especially joint or abdominal)

  • Anxiety or stress

  • Cognitive decline in senior pets

  • Digestive or urinary discomfort

Pets rarely complain, but sleep disruption tells the story.

Where Your Pet Sleeps Matters Too

Changes in sleep location are just as important as duration.

Notice if your pet:

  • Avoids favorite sleeping spots

  • Seeks cooler or harder surfaces

  • Moves closer to or farther from you

  • Chooses hidden or unusual places

These shifts often reflect changes in comfort, temperature regulation, or emotional needs.

Sleep and Emotional Wellbeing Are Closely Linked

Just like humans, pets process stress through sleep.

Major life changes can impact sleep:

  • Schedule changes

  • New caregivers or pets

  • Travel

  • Loss of a family member

  • Environmental noise or construction

Stress-related sleep changes often appear before other behavioral signs.

Cats: Masters of Quiet Sleep Signals

Cats are especially subtle.

Pay attention to:

  • Increased daytime sleeping with nighttime restlessness

  • Sleeping curled tightly instead of stretched

  • Reduced deep sleep postures

  • Hiding during rest periods

Cats often sleep through discomfort—but adjust how and where they rest.

When to Take Action

Consider consulting a veterinarian if sleep changes:

  • Persist more than a few days

  • Appear suddenly

  • Coincide with appetite, mobility, or behavior changes

  • Escalate over time

Early conversations prevent chronic issues, and unnecessary suffering.

Sleep isn’t just rest.
It’s regulation, recovery, and communication.

When your pet’s sleep changes, they’re telling you something, quietly, consistently, and honestly.

At Dogs On The Run, we believe truly attentive care means noticing what isn’t obvious, because that’s often where the most important information lives.
