Can I give my dog ibuprofen for pain?

No, never. Dogs are far more sensitive to ibuprofen than people, and there is no safe home dose. Vets can prescribe dog-specific anti-inflammatories such as carprofen or meloxicam that do the same job safely.

My dog ate one Advil. Is that an emergency?

Treat it as one. A single 200 mg tablet can cause stomach ulcers in a small dog, and risk rises steeply with dose and smaller body size. Call your vet or a poison hotline with your dog's weight and the strength of the tablet.

What does ibuprofen do to dogs?

It blocks prostaglandins that protect the stomach lining and maintain blood flow to the kidneys. The result is ulcers and vomiting first, then kidney failure at higher doses, and seizures in massive overdoses.

How soon do symptoms show after a dog eats ibuprofen?

Stomach signs like vomiting and loss of appetite often appear within hours, but kidney damage can develop over the following days. Absence of early symptoms does not mean the dog is safe.

Why ibuprofen is so dangerous for dogs

Ibuprofen works by blocking prostaglandins — but in dogs those same prostaglandins protect the stomach lining and keep blood flowing to the kidneys. Dogs also clear the drug slowly. The combination means doses people take casually can burn ulcers into a dog’s stomach, and larger amounts shut down the kidneys. Very high doses affect the brain and can cause seizures.

There is no safe way to give a dog ibuprofen at home. This applies to every brand: Advil, Nurofen, Motrin, Ibuprom and generics.

The real risks by scenario

A dog that grabs a dropped tablet is at risk of stomach ulcers, especially if small. A dog that chews through a bottle — which happens often, since some coatings taste sweet — is at risk of kidney failure and worse. Well-meaning owners dosing a limping dog cause many of these poisonings.

What to do if your dog ate ibuprofen

Call your vet or a pet poison hotline immediately with your dog’s weight and how many tablets are missing. Do not induce vomiting unless a professional tells you to. Treated early — decontamination, stomach protectants, IV fluids — most dogs do well. If your dog is in pain, ask your vet for a canine NSAID instead, and never reach for paracetamol or naproxen either.

If your dog ate it

If your dog swallowed ibuprofen, call your vet or a pet poison hotline immediately — do not wait for symptoms. Early treatment can prevent ulcers and kidney damage; waiting often cannot.
