“It’s Just Behaviour”… Or Is It Pain?

“It’s behavioural.”

That’s something I hear a lot from clients.

Sometimes they’ve decided this themselves.
Sometimes they’ve been told this by a professional.

My response?

It is behavioural.
But the real question is — how is that behaviour serving the dog?

Because behaviour isn’t random.
It’s communication.

And very often, it’s the first sign of pain.

Behaviour is information

One of the biggest shifts for me — both professionally and personally — was realising that a dog’s primary goal is simple:

Stay safe.

Once you see behaviour through that lens, everything changes.

Behaviours stop feeling stubborn, naughty or frustrating. Instead, they start to look like communication. 

Rather than asking,

“How do I stop this behaviour?”

I began asking,

“What is my dog trying to tell me — and how can I help?”

This made my life easier, because it gave me options to help. But it also helped me begin to understand when my dogs were in pain, because dogs are not always obvious and behaviour is often our first clue. 

Many pain-related behaviours are easy to misinterpret when we don’t know what’s behind them.

Reframing “problem” behaviours

Let’s look at some common labels we use:

Anxious - What if your dog already feels sore, and their tolerance for the world is lower?

Reactive - What if barking or growling is simply, “Please don’t come closer — I hurt”?

Stubborn - What if they physically can’t do what you’re asking?

Grumpy - How cheerful would you feel if every movement was uncomfortable?

Naughty - What if they’re just choosing what feels least painful?

When we reframe behaviour this way, compassion replaces frustration — and we start to notice the small changes earlier.

Subtle behaviour changes that may indicate pain

Not all signs of pain are obvious limping or yelps.

In fact, many dogs show much quieter, subtler changes first.

These can include:

• Becoming quieter or less energetic
• Sleeping more or seeming lethargic (pain is exhausting)
• Restlessness or struggling to get comfortable
• Increased grumpiness, reactivity or aggression
• Reluctance to walk, jump, or do previously enjoyed activities
• Noise sensitivity
• Playing less at home or on walks
• Pacing or inability to settle
• Excessive scratching or licking
• Groaning when lying down or getting up
• Using furniture or cushions to prop their head or body
• Sensitivity to touch
• Avoiding certain surfaces (slippery floors, stairs, uneven ground)

Sometimes changes even look positive at first.

An overly boisterous dog suddenly becoming “calm” can actually be a sign they’re moving less because something hurts.

If your dog seems different, it’s always worth asking why.

Musculoskeletal pain, osteoarthritis, and chronic conditions often develop gradually.

The earlier we notice changes, the sooner we can help.

Trust your instincts

You know your dog better than anyone.

If something feels “off”, even if you can’t quite explain it, trust that.

You’re not overreacting.
You’re advocating.

And that advocacy matters.

Need a bit of guidance?

If you’re unsure whether what you’re seeing could be pain-related, you don’t have to figure it out alone.

Through my ask a Therapist phone support calls, we can talk through the changes you’re noticing, explore possible patterns, discuss ways to support your dog’s comfort and movement, and help you prepare for conversations with your vet or wider care team.

I can’t diagnose or treat remotely — but I can help you make sense of what you’re seeing and feel more confident about your next steps.

Because understanding behaviour is often the first step towards easing pain.
