Pain in Dogs and Cats: Subtle Signs to Spot Early

Pain in dogs and cats is often silent: our companions don't complain the way we do. Instinctively, they hide their suffering—a reflex inherited from their wild ancestors, for whom showing weakness could be dangerous. The result is that many owners only notice a problem once it's already advanced. Learning to decode the signs of illness in cats and dogs allows you to act early, avoid complications, and know exactly when to see a vet.

Why pain often goes unnoticed

Contrary to what you might think, a suffering animal doesn't necessarily whine or cry out. Cats in particular are masters at hiding discomfort: they keep moving around, eat a little, and appear "normal" to a casual observer. Dogs, being more expressive, can still mask their pain through excitement or by clinging to their usual routine. That's why it's important to watch the small details of daily life rather than wait for an obvious complaint.

Behavioral changes to watch for

Behavior is often the first thing to change, before anything else becomes obvious.

• Withdrawal: the animal hides, avoids contact, or retreats to a quiet corner.
• Unusual irritability: a normally affectionate cat or dog that growls, hisses, or bites during a harmless petting session.
• Restlessness or lethargy: an inability to settle into a comfortable position, or conversely, unusual, prolonged stillness.
• Unusual vocalizations: plaintive meowing, or whimpering when lying down or getting up.
• Excessive or absent grooming: a cat that licks one spot obsessively, or stops grooming altogether.

Appetite, posture, and gait: valuable physical clues

Beyond behavior, an animal's body also tells a story.

Appetite-related signals

• Reduced or total loss of appetite, sometimes with gradual weight loss.
• Trouble eating: the animal approaches the bowl and then stops, a possible sign of dental or digestive pain.
• A sudden increase in thirst, which can accompany certain internal pain.

Postural signals

• A hunched back, lowered head, tail tucked against the body.
• Limping, or reluctance to jump, climb stairs, or play as usual.
• Faster or shallower breathing at rest.
• A prolonged hunched or crouched position, especially in cats suffering from abdominal pain.
• Trembling or visible stiffness when standing up.

What to do when you spot these signs: the right steps

As soon as a change lasts more than a day or gets worse, it's best not to wait. Here's a simple approach to follow:

1. Observe and take notes: when the change started, how often it occurs, and how it's progressing.
2. Check the environment: has anything changed recently (new food, a move, another pet) that could explain stress rather than pain?
3. Never give human medication: some human painkillers are toxic to dogs and cats.
4. See a vet promptly if several signs occur together, if the animal refuses to eat for more than 24 hours, or if the pain seems severe (crying out, total immobility, very rapid breathing).

A thorough examination by a professional remains the only reliable way to identify the exact cause of the pain and treat it properly. For a dog, you can check the directory of vets for dogs, and for a cat, the directory of vets for cats, to find a practitioner near you.

When to see a vet without delay

Certain signs call for immediate attention, with no waiting period: difficulty breathing, a swollen belly that's painful to the touch, a total inability to stand up, repeated vomiting, or pain so severe that the animal cries out at the slightest touch. When in doubt, it's always better to seek care too early than too late: a professional can quickly rule out an emergency or point you toward the right treatment.
