Pain vs Personality: When Behaviour Changes Are Body-Driven

How irritability, reactivity, and withdrawal often signal physical discomfort in dogs.

Introduction

“He’s just grumpy.” “She’s always been reactive.” “That’s just her personality.”

These explanations are common — and sometimes accurate. But in many cases, behaviour changes in dogs aren’t about temperament at all. They’re about physical discomfort that hasn’t been recognized yet.

Dogs don’t have words to say, “My shoulder hurts,” or “My back feels tight.” Instead, they communicate through behaviour. Subtle irritability, increased reactivity, avoidance, or withdrawal are often the body’s way of asking for help.

At Soul Paws Massage, we frequently work with dogs referred for “behaviour issues” — only to discover that muscle tension, stiffness, or chronic discomfort is playing a major role. When the body feels better, behaviour often follows.

Why Physical Discomfort Changes Behaviour

Pain and discomfort affect the nervous system. When something doesn’t feel right in the body, the brain shifts into a protective state.

This can lead to:

• Heightened alertness

• Lower tolerance for stress

• Faster emotional reactions

• Reduced ability to self-regulate

In other words, discomfort shortens patience.

Dogs aren’t choosing to be difficult — they’re responding to how their bodies feel.

Irritability: When Tolerance Shrinks

A dog who snaps more easily, growls during handling, or seems “touchy” may be experiencing ongoing physical tension.

Common discomfort-related triggers

• Being brushed

• Being harnessed

• Being touched in specific areas

• Having paws handled

• Being bumped accidentally

Muscle tension — especially in the neck, shoulders, hips, or back — can make normal interactions feel intrusive or uncomfortable.

Massage helps by:

• Releasing tight tissue

• Reducing protective guarding

• Improving comfort during handling

As discomfort decreases, tolerance often returns.

Reactivity: When the Body Is Already on Edge

Reactivity is often viewed purely as a training or emotional issue. But physical discomfort can significantly amplify reactive behaviour.

When a dog’s body feels tense or unstable:

• The nervous system stays in “alert mode”

• Startle responses increase

• Thresholds drop

• Recovery takes longer

A dog who reacts to:

• Other dogs

• Sudden noises

• Touch

• Crowded environments

…may be reacting from a place of physical vulnerability rather than fear alone.

Massage supports reactivity by:

• Calming the nervous system

• Improving body awareness

• Reducing muscle tension that keeps dogs on edge

A calmer body creates space for calmer responses.

Withdrawal: When Movement and Interaction Feel Too Hard

Some dogs don’t act out — they shut down.

Withdrawal may look like:

• Reduced interest in play

• Avoiding social interaction

• Sleeping more

• Moving less

• Staying in one spot

This behaviour is often mistaken for depression, aging, or laziness. In reality, withdrawal is a common response to ongoing discomfort.

When movement feels hard, dogs conserve energy.

Massage helps restore:

• Physical comfort

• Confidence in movement

• Willingness to engage

Owners are often surprised when withdrawn dogs become more interactive after addressing physical tension.

Why Behaviour Training Alone Isn’t Always Enough

Training is valuable — but it can’t override physical discomfort.

If a dog’s body hurts:

• Focus decreases

• Learning slows

• Frustration increases

• Behaviour modification becomes harder

Addressing the body first often makes training more effective, because the dog is no longer fighting discomfort while trying to learn.

Subtle Signs Behaviour Is Body-Driven

Behaviour changes linked to discomfort often include:

• Sudden onset without obvious trigger

• Worsening after activity or rest

• Sensitivity to touch in specific areas

• Resistance to gear or grooming

• Changes in movement or posture

• Improved mood after warming up

These clues suggest the body is involved — even if pain isn’t obvious.

How Massage Addresses Behaviour at the Source

Massage doesn’t “train” behaviour — it removes barriers to comfort and regulation.

Massage helps by:✔ Releasing muscle tension✔ Improving circulation✔ Supporting joint comfort✔ Calming the nervous system✔ Improving body awareness✔ Reducing stress hormones

When dogs feel safer in their bodies, they often:

• React less

• Engage more

• Recover faster

• Show improved mood

Behaviour shifts naturally when the body is supported.

Which Dogs Benefit Most from Body-Focused Behaviour Support

Massage is especially helpful for dogs who:

• Have sudden behaviour changes

• Are reactive without clear cause

• Avoid handling

• Seem “moody” or unpredictable

• Are aging or slowing down

• Have a history of injury

• Experience anxiety or stress

Supporting the body can be a missing piece in their care.

A Compassionate Reframe

Behaviour is communication.

When dogs act differently, they’re telling us something has changed — often internally. Reframing behaviour as information rather than defiance allows us to respond with empathy and appropriate support.

Why Early Intervention Matters

The longer discomfort goes unaddressed:

• The more ingrained behaviour patterns become

• The more compensation builds

• The harder recovery becomes

Early massage support can prevent behaviour shifts from becoming chronic.
