Recognizing Hidden Pain in Senior Dogs — Calgary

Dogs don't yelp when they're in chronic pain. They adjust. They compensate. They keep eating, keep greeting you at the door, keep appearing fine — while quietly managing significant discomfort. This evolutionary instinct to mask weakness means that by the time a dog is obviously suffering, the pain has often been present for months.

Key Context

Why This Matters

Educational

Chronic pain is widely under-treated in dogs precisely because the signs are subtle and easy to attribute to aging. The 2022 AAHA Pain Management Guidelines estimate that 50–90% of senior dogs have chronic pain of some kind — and the majority are not being treated for it. Recognizing pain early changes treatment outcomes significantly. Managed pain means better mobility, better behavior, and a better quality of life.

Evidence-Based

Key Facts

Dogs evolved to hide pain — showing weakness within a pack or to predators was dangerous. Modern dogs inherit this instinct fully intact.

50–90% of senior dogs experience chronic pain of some kind — the majority are estimated to be under-diagnosed and under-treated.

Behavioral changes — withdrawal, reduced affection seeking, unusual irritability — are among the earliest and most reliable pain indicators in dogs.

A dog that is 'still eating fine' can simultaneously be in significant chronic pain — appetite is not a reliable indicator of comfort level in dogs.

Action Steps

What Owners Should Do

Practical steps you can take right now.

  1. 1

    Watch for behavioral changes, not just physical ones — withdrawal from family interaction, reduced initiative in play, changes in where the dog sleeps are early pain signals.

  2. 2

    Observe how the dog rises from rest — stiffness for the first 5–10 minutes after lying down is a classic chronic pain pattern, not just 'being old.'

  3. 3

    Note any changes in posture — a dog carrying weight forward onto front legs, tucking the abdomen, or standing with a hunched back is compensating for rear or spinal pain.

  4. 4

    Watch for self-grooming changes — excessive licking of a specific joint or limb indicates localized discomfort; reduced grooming of painful areas is equally significant.

  5. 5

    Ask your vet to use a validated pain scale (Glasgow Composite Pain Scale, Colorado State Pain Scale) at every senior exam — don't rely on a general impression.

  6. 6

    If your dog shows any facial tension at rest — tightened brow muscles, ears drawn back or sideways, orbital tightening — take a photo and show your vet; the Canine Grimace Scale can be applied.

  7. 7

    Tell observers (daycare team, trainer, groomer) what you're watching for — consistent external observers often notice gait or behavioral changes before owners do.

Red Flags

Warning Signs to Watch For

Know when something needs attention.

  • Rising stiffness — a dog that takes several steps before moving normally after rest, especially in the mornings or after napping.
  • Gait abnormalities: bunny hopping with rear legs, wide rear stance, asymmetric weight bearing, toe dragging during the swing phase of walking.
  • Behavioral changes: irritability when touched in specific areas, reduced tolerance for grooming, new aggression around handling — these are frequently pain-driven, not personality changes.
  • Panting at rest without heat or exertion — a recognized pain indicator in dogs that owners frequently dismiss.
  • Changes in sleep — restlessness, frequently repositioning, seeking new sleeping surfaces — indicates the dog cannot find a comfortable position.
When to See a Vet

Any new behavioral change in a senior dog — irritability, withdrawal, reduced activity — warrants a veterinary exam focused on pain assessment. Don't wait for limping or obvious distress. Bring your observations and any photos or video of the behavior changes. Ask specifically for a pain assessment, not just a general wellness exam — framing the visit around pain puts the right lens on what the vet is looking for.

From the Pack

The PAWS Perspective

What We See

Our team watches 15–20 dogs a day. We notice gait changes, reluctance to engage with the pack, unusual postures during rest, and changes in how a dog approaches the pack walk. Dogs who are quietly in pain often show it in these small ways — and we see them clearly because we're watching closely and consistently.

How Daycare Connects

We're not veterinary diagnosticians. But we're consistent, attentive observers with 16 years of watching dogs move, rest, socialize, and change. When we notice something, we say something — directly and honestly. Owners hear from us about gait changes, behavioral shifts, and reluctance to engage more often than they might expect. We think that's part of what we're here for.

Eric's Take
"I've flagged pain concerns to owners dozens of times. Not always confidently — sometimes it's a 'have you noticed this?' rather than a 'I'm certain this dog is hurting.' But I've learned that the subtle things are worth naming. The owners who follow up with their vet almost always come back and tell me the vet found something. It matters to say something."

— Eric Yeung, Owner, PAWS Dog Daycare

Honest Note

Recognizing pain is not the same as diagnosing or treating it. When we flag something, we're giving you an observation — not a clinical assessment. Your vet makes the diagnosis. We just don't stay quiet when something looks off.

Common Questions

Recognizing Hidden Pain in Senior Dogs — FAQs

My dog still wags his tail and greets me at the door. Can he really be in pain?
Yes. Dogs in chronic pain maintain social behaviors — greeting, tail wagging, eating — because those behaviors are deeply wired. They're not faking wellness; they're genuinely happy to see you while also being in pain. The two are not mutually exclusive. The signs of pain appear in the quieter moments: how they rise, how they move when they think no one is watching, how they position themselves when resting.
How is chronic pain different from acute pain in dogs?
Acute pain — from an injury or procedure — often produces more obvious signs: vocalization, guarding, flinching. Chronic pain is persistent background discomfort that the dog has adapted to behaviorally. The subtle signs of chronic pain are behavioral and postural rather than vocal. That's why it's so easily missed.
What is the Canine Grimace Scale?
A validated pain assessment tool based on facial action coding. It scores: orbital tightening (squinting), ear position (pulled back or flattened), raised cheeks (tension around the muzzle), and whisker position. A dog in pain often shows multiple of these simultaneously. It's designed for acute pain assessment but is also useful for identifying chronic pain in resting dogs. Your vet can apply it formally, but photos taken at home during rest are valuable evidence.
My dog used to love daycare and has been going less enthusiastically. Should I be concerned?
Yes — reduced enthusiasm for previously loved activities is a meaningful signal. It could be pain, cognitive changes, or simply a life stage shift — but it warrants a veterinary look rather than an assumption that the dog is just getting older. At PAWS, we'd flag this to you directly and suggest a vet visit. We take behavior changes in our regulars seriously.
What pain management options exist beyond NSAIDs?
A multimodal approach is the standard: NSAIDs as first-line, gabapentin for neuropathic pain, Adequan for joint disease, physical rehabilitation (hydrotherapy, therapeutic exercise), laser therapy, acupuncture, and weight management. For dogs who cannot tolerate NSAIDs due to organ disease, gabapentin and physical therapy are the primary alternatives. Your vet can build a protocol specific to your dog's diagnosis and health history.
