Recognising Pain in Pets: The Subtle Signs Owners Miss

Signs of pain in pets: why the early ones are so easy to miss

Signs of pain in pets rarely look like the whimpering or limping most owners expect. Cats and dogs are hardwired to hide discomfort — a survival instinct left over from life in the wild, where looking weak made them a target. That means the first clues are usually small: a slightly shorter walk, a missed jump onto the sofa, or a bit more time spent alone. Catching these early changes matters, because pain that goes unnoticed for weeks or months is harder to treat and harder on your pet.

With 11.1 million dogs and 10.5 million cats now living in UK households, according to the PDSA's 2025 PAW Report, this is a welfare issue affecting millions of homes. The same research found that while three in ten owners believe they'd know what to do in a pet emergency, most struggle when asked about specific scenarios — pain recognition included.

What to watch for: the subtle signs owners often miss

Pain doesn't announce itself. It shows up as small shifts in everyday behaviour that are easy to write off as "getting older" or "just having an off day". Keep an eye out for:

• Changed sleep patterns — restlessness, sleeping in unusual positions, or sleeping noticeably more than normal
• Reduced grooming — a cat's coat looking greasy, matted, or unkempt is a classic early warning sign
• Reluctance to jump, climb stairs, or go on full walks
• Clinginess or, conversely, hiding away more than usual
• Eating more slowly, dropping food, or avoiding hard biscuits and chews
• Facial changes — increased blinking, looking away, or a tense, "worried" expression
• Excessive licking or chewing at one part of the body
• A drop in playfulness or no longer greeting you at the door

Any one of these on its own might mean nothing. But a pattern of change from your pet's normal baseline is worth a call to your vet — you know your animal better than anyone, and you don't need to diagnose the cause yourself to justify asking for help.

Cats hide pain differently to dogs

If you share your home with a cat, be extra vigilant. Cats are notoriously good at masking illness and discomfort, often right up until a condition becomes serious. Vets describe this as "silent pain" — a cat can be managing significant joint pain or internal discomfort while still eating, using the litter tray, and appearing largely normal to an untrained eye. Watch specifically for a cat spending more time in high-up or hidden spots, reduced interest in play, or reluctance to be touched or picked up in a particular spot.

Dogs are generally more expressive, but even they will often "push through" pain for a walk or a game of fetch, especially breeds bred for stoicism like working and sporting dogs. Don't take enthusiasm at face value — watch how they move and recover afterwards, not just how eager they seemed beforehand.

When to call your vet immediately

Some signs need same-day attention rather than a watch-and-wait approach. Contact your vet urgently if your pet is crying out, growling or hissing when touched in a specific spot, holding a limb up entirely, unable to settle in any position, or showing swelling, heat, or visible distress. The RSPCA and PDSA both note that while severe pain is usually obvious, it always warrants prompt veterinary attention rather than home management — pain relief formulated for humans, including paracetamol and ibuprofen, can be dangerous or fatal for pets and should never be given.

Keeping a record so nothing gets missed

Because pain builds gradually, it's genuinely hard to remember whether your dog started limping "a bit" three weeks ago or just yesterday. A simple written or photo log — even a few notes on your phone — makes it far easier for your vet to spot a pattern, and far easier for you to notice one yourself.

This is also where keeping your pet's profile up to date pays off. A [PawLink](/#features) tag's medical notes tab means any vet, pet sitter, or family member who scans it can see known conditions, medications, and recent changes at a glance — useful if a pain flare-up happens while someone else is looking after your pet, or if you need to describe a timeline accurately during a vet visit. It's a small habit, but one that supports faster, better-informed care.

The bottom line

Trust your instincts. If something about your pet feels "off" — even if you can't quite name it — that instinct is usually rooted in genuine, if subtle, behavioural change. Visit the [PawLink Safety Hub](/safety-hub) for more UK-focused pet safety guides, and if you don't already have a way to keep your pet's medical history accessible to anyone who might need it in an emergency, it's worth setting one up before you need it, not after.
