Pain and Anxiety in Pets Aren't Always Obvious

One of the hardest things about caring for an aging or sick pet is that they can't tell you how they feel. Worse, they're often actively hiding it. By the time pain or anxiety becomes obvious to you, it's usually been present for weeks — sometimes months — and your pet has been quietly suffering through it.

Recognizing the subtle signs is one of the most important skills a pet owner can develop. This article covers what to look for, why pets hide what they're feeling, and what to do once you start noticing it.

Why Pets Hide Pain

Hiding pain is an evolutionary survival mechanism. In the wild, an animal that visibly shows weakness becomes a target — for predators, for rivals, for anyone looking for an easy meal. So animals are wired to mask discomfort and keep functioning as normally as possible, even when they're hurting badly.

Cats are especially good at this — they're solitary hunters whose ancestors had no one to rely on if they got sick. But dogs hide pain too, just differently. A dog might still wag and greet you because the social bond is strong, while privately struggling to get up the stairs or settle in for the night.

The takeaway: just because your pet "seems fine" doesn't mean they are.

Subtle Signs of Pain in Dogs

Dogs in chronic pain often don't whimper, limp, or cry out. Instead, watch for:

• Reluctance to jump on the couch or bed they used to jump on easily
• Slowing down on walks, sitting down to rest, or wanting to turn back early
• Panting at rest, especially when the room is cool
• Difficulty getting up after lying down — a slight pause, a stiff first few steps
• Avoiding stairs or taking them one at a time
• Restlessness at night — pacing, repositioning, unable to settle
• Loss of interest in toys, walks, or play
• Hunched posture or "tucked" stance with weight shifted backward
• Excessive licking of one body part — joints, paws, abdomen
• Withdrawing from the family — sleeping more in another room
• Subtle personality changes — less affectionate, snappier, or quieter

Subtle Signs of Pain in Cats

Cats are even harder to read than dogs. The signs are often almost invisible:

• Reduced grooming — coat becomes greasy, matted, or unkempt
• Hiding more than usual — under beds, in closets, behind furniture
• Reduced jumping — staying on the floor instead of climbing to favorite perches
• Sitting in a hunched posture with paws tucked tightly under
• Squinting or "half-closed" eyes, especially when at rest
• Reluctance to use the litter box (or eliminating just outside it)
• Increased irritability — swatting, growling, hissing at things they used to tolerate
• Excessive purring — yes, cats purr in pain too, as a self-soothing mechanism
• Changes in sleep posture — no longer stretching out, always curled tightly
• Loss of appetite or eating very slowly

If you have a cat and you're noticing several of these, take it seriously. Cats are masters at compensating, and by the time their pain is visible, it's usually significant.

Anxiety Often Travels With Pain

Anxiety is the other thing pets hide — and it often shows up alongside pain. A pet who's hurting may also be afraid: afraid of the next time it will hurt, afraid of being touched, afraid of being moved. Watch for:

• Restlessness or pacing, especially in the evening
• Trembling or shaking that's not related to cold
• Yawning or lip-licking when nothing food-related is happening
• Avoiding eye contact or turning away when approached
• Clinginess — wanting to be near you constantly, or hiding from you
• Vocalizing at night — whining, crying, or pacing in the dark
• Sudden startling at small noises
• Loss of bladder or bowel control in animals who have always been reliable

For a sick or aging pet, anxiety can be just as miserable as physical pain — and it often goes unaddressed because it's harder to see and harder to medicate.

What to Do When You See These Signs

The first step is always to talk to your veterinarian. Pain and anxiety in pets are almost always treatable — even when the underlying condition isn't curable. A good vet will work with you on a layered approach:

• Pain medication — NSAIDs, gabapentin, opioids depending on cause and severity
• Anti-anxiety medication — trazodone, gabapentin (which helps both pain and anxiety), or others
• Environmental adjustments — orthopedic beds, raised food bowls, ramps, non-slip rugs, nightlights
• Routine adjustments — shorter walks, more rest, predictable meal times
• Comfort measures — warmth, gentle massage, calming music or pheromone diffusers

Many families are surprised at how much a pet's quality of life can improve once pain and anxiety are properly managed. Sometimes a pet who seemed close to the end has months of comfortable life ahead of them once the right combination of medication and adjustments is in place.

When Management Isn't Enough Anymore

That said, there comes a point with progressive disease where pain and anxiety can no longer be controlled to a level that allows quality of life. This is one of the clearest signals that it may be time to consider euthanasia. We've written about how to assess this here.

If your pet is on multiple medications and still showing daily signs of distress, your vet has run out of next options, and the bad moments are outnumbering the good — the kindest thing left to do is often to let them go. Continuing to medicate a pet who is still in pain isn't keeping them alive. It's prolonging the part of life they would not choose.

Trust What You're Seeing

The most important thing is to trust your own observation. You spend more time with your pet than any veterinarian ever will. If you sense something is wrong — even if you can't articulate exactly what — you're probably right. Animals communicate through small changes, and the people who love them are usually the first to notice. Don't dismiss what you're seeing. Don't wait for it to become obvious. By then, your pet has been suffering for a long time.
