How can I tell if my dog or cat is in pain?

Pets hide pain, so watch for subtle changes: limping or stiffness, reluctance to jump or move, hiding, reduced appetite, panting at rest, a hunched or tucked posture, whimpering or growling when touched, excessive licking of one spot, restlessness, and trembling. Any sudden change in normal behavior can signal pain.

What are signs of a pet emergency?

Call a vet or emergency hospital immediately for difficulty breathing, collapse or extreme weakness, pale, white, or blue gums, a bloated hard belly with retching, seizures, inability to urinate, heavy bleeding, suspected poisoning, or sudden inability to use the legs. These are life-threatening.

Can I give my pet pain medicine at home?

No — never give human pain relievers like ibuprofen, acetaminophen (Tylenol), aspirin, or naproxen to dogs or cats. They are toxic and can be fatal. Only give pain medication prescribed by your veterinarian, at the exact dose they specify.

Why pets hide pain

In the wild, showing weakness makes an animal a target, so dogs and cats instinctively mask discomfort. That's why pain often shows up as subtle behavior changes rather than obvious crying. You know your pet's normal best — a quiet dog who suddenly won't jump on the couch, or a social cat who starts hiding, is telling you something.

The most reliable signs of pain

Movement: limping, stiffness, slowing down, trouble with stairs or jumping.
Posture: hunched back, tucked belly, lowered head, a "praying" stretch (front down, rear up — a sign of belly pain).
Behavior: hiding, clinginess, irritability, less play, restlessness.
Body focus: licking, biting, or protecting one area.
Vital changes: panting at rest, trembling, eating less, changes in sleep or toileting.

Never give human painkillers

This is one of the most important rules in pet care: never give ibuprofen, acetaminophen (Tylenol), aspirin, or naproxen to a dog or cat. They are toxic and can cause kidney failure, stomach ulcers, or death — acetaminophen is especially deadly to cats. Only ever use pain medication prescribed by your vet.
