How to Recognize Pain in Dogs and Cats Before It Gets Worse

How to Recognize Pain in Dogs and Cats Before It Gets Worse 🐶🐱

By Dr Duncan Houston

🔎 Quick Answer

Pets often show pain through behaviour changes, reduced mobility, altered appetite, unusual vocalisation, grooming changes, and toileting issues. Early signs are often subtle, especially in cats and older pets, so noticing small changes quickly can make a big difference to comfort and treatment.

Your pet cannot tell you “this hurts,” but that does not mean they are not communicating.

Pain in dogs and cats is often easy to miss because it rarely looks dramatic at first. Sometimes it is a dog hesitating before jumping into the car. Sometimes it is a cat using the litter tray differently. Sometimes it is just a pet who seems a little “off” and not quite themselves.

As a veterinarian, I can tell you this: those small changes matter. Catching pain early can improve comfort, mobility, appetite, sleep, and quality of life long before things get worse.

🧠 Behaviour and Personality Changes

One of the earliest signs of pain is often a change in behaviour.

Watch for:

• Less interest in affection or play

• Hiding more than usual

• Irritability or aggression when touched

• Reduced curiosity or interaction

• Avoiding favourite spots or routines

A pet in pain may seem grumpy, withdrawn, or “not themselves.” Sometimes owners think their pet is just being moody. Usually, pets are not trying to be dramatic. They are just uncomfortable and doing their best with the tools they have.

👀 Changes in Body Language and Appearance

Pain often shows up in posture and grooming.

Look for:

• Repeated licking or chewing of one area

• Matted, scruffy, or poorly maintained coat

• Tense body posture

• Hunched back or lowered head

• Squinting or changes around the eyes

• Weight loss or weight gain

Some pets also look “tight” through the face or body. Once you notice it, you cannot unsee it.

🍽️ Changes in Eating and Drinking

Pain can turn a normally food-loving pet into a hesitant one.

Signs include:

• Reduced appetite

• Slower chewing

• Dropping food

• Pawing at the mouth

• Drooling

• Avoiding hard food or certain textures

• Less enthusiasm at mealtimes

Dental pain is a big one here, but it is not the only cause. Neck pain, abdominal pain, nausea, and systemic illness can all affect eating too.

🔊 Vocal Changes

Some pets get louder when they hurt. Others get quieter.

Possible signs:

• Whining

• Whimpering

• Crying out

• Growling when touched

• Hissing or spitting in cats

• Unusual howling or restlessness at night

A pet that suddenly becomes more vocal, or strangely silent, may be trying to tell you something is wrong.

🏃 Movement and Mobility Changes

This is one of the biggest categories, especially in older pets.

Watch for:

• Reluctance to jump, run, or climb stairs

• Limping or favouring a leg

• Difficulty getting up

• Panting more during activity

• Stiffness after rest

• Slowing down on walks

• Sleeping in odd positions or changing resting spots

A lot of owners say, “I thought he was just getting old.” Fair enough, but many pets are not “just old.” They are sore.

🚽 Bathroom Habit Changes

Pain often affects toileting, and this gets missed more than it should.

Look for:

• Accidents indoors

• Cats toileting outside the litter tray

• Straining to urinate or defecate

• Crying in the litter tray or outside

• Going more or less often than usual

• Trouble posturing to urinate or defecate

In cats, these signs may be related to arthritis, bladder pain, constipation, or stress. In dogs, they may point to joint pain, abdominal pain, spinal discomfort, or urinary problems.

😼 Why Cats Hide Pain So Well

Cats are professionals at acting fine when they are absolutely not fine.

In the wild, showing weakness could make them vulnerable, so many cats instinctively hide signs of discomfort. That means their pain signs can be very subtle.

Common cat pain signs include:

• Hiding more

• Grooming less or over-grooming one area

• Changes in appetite

• Reduced jumping

• Different litter tray habits

• Less social interaction

• Sleeping more in unusual places

If your cat has changed even slightly, do not brush it off. Cats rarely fill out a complaint form.

🎂 Older Pets and the “Just Ageing” Trap

This one catches people all the time.

Many signs blamed on age are actually signs of treatable pain:

• Sleeping more

• Playing less

• Avoiding stairs

• Becoming less interactive

• Struggling to get comfortable

• Less enthusiasm for walks or food

Arthritis, dental disease, spinal pain, and internal disease are common in older pets. A lot of senior pets feel dramatically better once their pain is recognised and managed properly.

🩺 What To Do If You Suspect Pain

If you think your pet may be painful, do not wait and see for too long.

Practical steps:

• Book a veterinary examination

• Keep a diary of changes in appetite, movement, sleep, and behaviour

• Record videos of anything abnormal

• Note when signs are worse, such as after exercise or overnight

That information can be incredibly helpful for your vet.

💊 Pain Management Options

The good news is that veterinary pain control has come a long way.

Depending on the cause, treatment may include:

• Prescription pain relief

• Anti-inflammatory medication

• Dental treatment

• Joint supplements

• Weight management

• Physiotherapy or hydrotherapy

• Massage and rehabilitation

• Orthopedic beds and ramps

• Heat or cold therapy in selected cases

For dogs with mobility issues, supportive home changes can help too, like better flooring grip, easy-access bedding, and ramps instead of stairs. An orthopedic bed can make a big difference for sore joints, especially for seniors and dogs with arthritis. The WOOPF™ SNÖR Vet Orthopedic Low-Entry Lavender Memory Foam Bed is designed specifically to make resting and getting in and out easier for dogs with mobility concerns.

🚨 When To See a Vet Urgently

Some pain signs need urgent attention.

See a vet as soon as possible if your pet:

• Cries out suddenly or repeatedly

• Cannot get up

• Stops eating completely

• Has trouble breathing

• Strains to urinate

• Has a swollen abdomen

• Becomes suddenly aggressive or distressed

• Seems weak, collapsed, or disoriented

Pain is not something to “tough out,” and pets are often much worse than they look.

💬 Final Thoughts

You know your pet better than anyone.

If something feels off, trust that instinct. Pain often begins quietly, but early recognition can prevent a lot of suffering and improve your pet’s everyday life in a very real way.

A missed jump, a grumpy reaction, a quiet cat hiding under the bed, these things can all be the start of an important story.

The earlier we listen, the better we can help.

❓ FAQ

What is the most common sign of pain in pets?

Often it is a behaviour or mobility change, such as slowing down, avoiding stairs, or becoming withdrawn.

Do cats show pain differently from dogs?

Yes. Cats often hide pain much more subtly, so changes in grooming, appetite, hiding, or litter tray use can be important clues.

Is slowing down always just old age?

No. Many older pets are painful rather than simply “old,” and treatment can make a huge difference.

Should I give my pet human painkillers?

No. Many human pain medications are dangerous or toxic to dogs and cats. Always speak to a veterinarian first.
