How to Know if My Pet is in Pain: Signs to Watch Out For

Identify if your pet is in pain It's not always simple. Animals, by instinct, mask discomfort as a survival mechanism, making it essential that guardians develop a watchful eye.

Knowing if my pet is in pain requires careful observation of behavior, posture, and even small changes in routine.

According to the American Veterinary Medical Association (AVMA), more than 60% of dogs and cats over seven years of age develop painful joint diseases, which are often underdiagnosed.

Pain in pets can be acute (such as after an injury) or chronic (such as in cases of osteoarthritis), and each type requires different approaches.

While some signs are obvious, such as limping or whining when touched, others are subtle, such as a reluctance to climb stairs or a loss of interest in play.

This detailed guide explores everything from physical changes to emotional changes, with practical examples to help owners respond quickly.


Behavioral Signs: When Your Pet Isn't Acting Normally

Sudden changes in behavior are the first warning signs. A docile animal that becomes aggressive when handled or an active pet that spends hours hiding may be suffering.

Aversion to touch in specific areas, such as the paws or abdomen, is also a clear sign of localized discomfort.

Cats, for example, tend to isolate themselves when they feel pain, seeking high or dark places to protect themselves.

Dogs may also be restless, standing up and lying down repeatedly, as if they cannot find a comfortable position.

Excessive licking of a specific area (such as a joint) is another common behavior, as salivation releases endorphins that temporarily relieve pain.

Additionally, pets with chronic pain may develop anxiety or even depression.

A dog that once loved walks and now refuses to leave the house, or a cat that stops interacting with the family, deserves immediate veterinary investigation.

Physical Changes: The Body Says What the Pet Doesn't Say

Body posture never lies. A pet in pain may arch its back (common in cats with cystitis or urinary obstruction) or limp (indicative of joint injuries or fractures).

Other physical signs include:

  • Pupil dilation (associated with acute pain, such as cramps or trauma)
  • Rapid breathing for no apparent reason (especially at rest)
  • Muscle tremors or stiffness (common in degenerative diseases such as myelopathy)

The table below details symptoms and their possible causes:

Clinical SignPossible CausePractical Example
Limping or limpingOsteoarthritis, fracture or sprainDog avoids putting weight on hind leg when walking
Loss of appetiteDental or gastrointestinal painCat chews on only one side of its mouth
Difficulty jumpingHip dysplasia or injuryCat stops climbing on the couch

Additionally, facial expression changes: half-closed eyes, low ears, or a tense snout can indicate distress.

Brachycephalic breeds (such as Bulldogs and Pugs) deserve extra attention, as they already have difficult breathing by nature.

Changes in Daily Habits: Broken Routines

Pets are creatures of habit, and any change in routine can be a warning sign. If your pet stops climbing on the couch, avoids stairs, or takes a long time to get up after sleeping, investigate.

A reduction in water or food consumption also deserves attention, as it may indicate dental pain, nausea, or even kidney problems.

Cats in pain, for example, may neglect grooming, resulting in matted or dirty fur.

Dogs may urinate more or less than usual due to abdominal discomfort or infections. Other signs include:

  • Excessive sleep or insomnia (chronic pain disrupts rest)
  • Difficulty positioning oneself to relieve oneself (common in pets with arthritis)
  • Loss of interest in favorite toys or activities

A practical example: a dog that always ran to the door when he heard the sound of his collar, but now only watches from afar, may have joint pain.


Emotional Signals: Pain Affecting Mood

Apathy, irritability, or even depression can be linked to chronic pain.

A study of University of Lincoln (2024) showed that 40% of older cats have mood swings due to untreated diseases such as osteoarthritis or hyperthyroidism.

If your pet has stopped playing, doesn't respond to stimuli, or seems "disconnected," a veterinarian should be consulted. Animals don't cry like humans, but their suffering is real. Emotional signs include:

  • Sudden aggression (a cat that never bitten starts to attack when touched)
  • Destructive behavior (anxious dogs may chew furniture due to the stress of pain)
  • Excessive vocalization (meowing or barking at unusual times)

Older pets are most affected, but younger pets can also develop pain due to trauma or congenital diseases.


When to Look for a Veterinarian?

Don't wait for your pet to scream in pain before taking action. If you notice any of these signs, schedule an appointment:

  • Excessive vocalization (abnormal whining, meowing, especially at night)
  • Difficulty moving (reluctance to jump, climb stairs or run)
  • Sudden aggression (growling or biting when handled)

Tests such as X-rays, ultrasounds, and blood tests help identify the source of the problem. In cases of chronic pain, physical therapy and veterinary acupuncture can improve quality of life.


How to Help a Pet in Pain?

In addition to veterinary treatment, guardians can adopt palliative measures:

  • Orthopedic beds (reduce pressure on joints)
  • Access ramps (prevent pets from jumping on the sofa)
  • Balanced diet (prevents obesity, which worsens joint pain)

Supplements such as chondroitin and omega-3 also help with joint health, but always under professional guidance.


Conclusion

Knowing if my pet is in pain it is a responsibility that requires continuous attention.

Behavioral, physical, and emotional signs, when interpreted correctly, can prevent prolonged suffering and serious complications.

Never underestimate subtle changes – your watchful eye is your animal’s best defense.

Consult a veterinarian regularly, especially for older pets or those with a history of chronic illnesses.

After all, relieving pain is not only an act of care, but of love and respect for the life we share with them.


Frequently Asked Questions

1. My pet is limping, but doesn't seem to be in any pain. Should I be concerned?
Yes. Some animals instinctively mask pain. A limp can indicate anything from a simple injury to a fracture or osteoarthritis.

2. Do cats hide pain better than dogs?
Yes. Cats are more discreet and tend to isolate themselves when they're feeling unwell. Dogs, on the other hand, can vocalize or become more needy.

3. What is the best pain reliever for pets?
Never self-medicate your pet. Human anti-inflammatories, such as dipyrone, can be toxic. Consult a veterinarian.

4. How to differentiate chronic pain from acute pain?
Acute pain appears suddenly (such as after a fall), while chronic pain persists for weeks (such as with arthritis). Both require veterinary monitoring.

5. Do older pets feel more pain?
Yes. Degenerative diseases, such as osteoarthritis and dental problems, are common in older animals. Annual checkups are essential.
