Emergency exposure: call now

Also sold as Advil, Motrin, Nurofen, Midol (some versions), generic ibuprofen

At amounts a dog can reach in a normal household, this needs a vet or poison-control call straight away rather than watching and waiting.

DogSafe severity score
8/10Dangerous at any amount

No. There is no safe at-home dose of ibuprofen for a dog, and vets do not prescribe it: dogs clear it far more slowly than people do, so an amount that is unremarkable in a person concentrates in a dog. If your dog has eaten any, call a vet or poison control now rather than waiting for symptoms.

Call a vet or poison control now. Do not wait for symptoms.

Exposure details to have ready

These are the questions a veterinarian or poison-control operator will ask. Fill in what you know and leave the rest blank. This tool does not estimate a dose or a risk score: medication risk depends on the exact ingredient, strength, and formulation, so the assessment has to come from the clinician on the call.

Signs so far
Before you call
  • Keep the package, blister pack, or prescription bottle. The strength and the full ingredient list are what make the advice specific.
  • Do not induce vomiting unless a veterinarian or poison-control professional tells you to. It is the wrong move for several medications and can cause harm on its own.
  • Do not give milk, food, salt, hydrogen peroxide, or any home remedy on your own.
  • Do not give a second dose of anything to make up for one you think was missed.
  • Count what is left in the packet, so the number missing can be worked out.

Why Ibuprofen is dangerous

Ibuprofen blocks the enzymes that maintain the stomach's protective lining and the blood supply to the kidneys. In people those effects are usually tolerable; dogs eliminate the drug much more slowly, so the same tablet keeps working far longer. The result is stomach ulceration and kidney injury, and at higher exposures the nervous system is affected as well. It is consistently among the most common causes of medication poisoning in dogs reported to poison-control services.

For related dog-safety questions and product-by-product answers, see the complete naproxen guide.

How soon do signs appear?

Stomach signs usually come first, often within hours, and kidney effects can take a day or more to become visible. That gap matters: a dog that seems fine the evening it happened is not evidence that the exposure was harmless, and the treatments that protect the stomach and kidneys are most useful before damage shows.

200 mg tablets versus 800 mg prescription tablets

An over-the-counter tablet and a prescription-strength one differ fourfold in a package that looks much the same. Liquid gels and children's suspensions differ again. Read the milligram figure off the packet rather than describing the tablet by size or colour: it is the single number that changes the assessment most.

What poison control will ask you

Your dog's weight; the exact product and its strength in milligrams per tablet; how many are unaccounted for; how long ago; whether it was an extended-release or combination product; what else your dog takes; and what signs you are seeing. Have the packet in your hand when you call rather than trying to recall the strength.

Signs to watch for

Vomiting (sometimes with blood), loss of appetite, black tarry stools, belly pain, increased thirst and urination, lethargy, weakness; at high exposures wobbliness or seizures

What to do next

Call first, then gather the packet, count what is left against what should be there, note the strength and the time, and keep your dog from eating or drinking anything else until you have advice.

A closer look at ibuprofen

Ibuprofen blocks the enzymes that maintain the stomach's protective lining and the blood supply to the kidneys. In people those effects are usually tolerable; dogs eliminate the drug much more slowly, so the same tablet keeps working far longer. The result is stomach ulceration and kidney injury, and at higher exposures the nervous system is affected as well. It is consistently among the most common causes of medication poisoning in dogs reported to poison-control services. The details below use the specific facts for this exposure, rather than treating it like every other medication question.

1. Start with the exact exposure

For a closely related comparison, read Naproxen. There is no home dose. Vets have dog-specific NSAIDs (carprofen, meloxicam and others) precisely because the human ones are a poor fit, so there is no situation in which working out a fraction of a human tablet is the right move. What matters after an exposure is the strength in milligrams, the number missing, your dog's weight and how long ago it happened.

2. Use the facts to decide whether to monitor or call

Another helpful reference is Acetaminophen. Nothing to manage at home. Call a vet or an animal poison-control line before symptoms appear, because the treatment that protects the stomach and kidneys works best when it is started early. Do not induce vomiting unless you are told to. Immediately, for any suspected amount, and without waiting to see whether your dog becomes unwell. Go straight in for vomiting with blood, black tarry stools, sudden thirst or increased urination, weakness, wobbliness, or seizures.

3. If the details are uncertain

Follow the first 10 minutes guide. Call first, then gather the packet, count what is left against what should be there, note the strength and the time, and keep your dog from eating or drinking anything else until you have advice.

FAQ

How much Ibuprofen is dangerous?

There is no home dose. Vets have dog-specific NSAIDs (carprofen, meloxicam and others) precisely because the human ones are a poor fit, so there is no situation in which working out a fraction of a human tablet is the right move. What matters after an exposure is the strength in milligrams, the number missing, your dog's weight and how long ago it happened.

Can I treat this at home?

Nothing to manage at home. Call a vet or an animal poison-control line before symptoms appear, because the treatment that protects the stomach and kidneys works best when it is started early. Do not induce vomiting unless you are told to.

When should I call the vet?

Immediately, for any suspected amount, and without waiting to see whether your dog becomes unwell. Go straight in for vomiting with blood, black tarry stools, sudden thirst or increased urination, weakness, wobbliness, or seizures.

Can I give my dog ibuprofen for pain?

No. Vets do not prescribe ibuprofen to dogs, and there is no at-home dose to scale down to. If your dog is in pain, that is a reason to call your vet, who has NSAIDs licensed for dogs and can pick one that suits your dog's kidneys, liver and other medications.

My dog ate one ibuprofen and seems fine. Do I still need to call?

Yes. The important effects on the stomach and kidneys are not visible from the outside early on, and one tablet is a very different exposure for a 6 lb dog than for an 80 lb one. A poison-control call costs a consultation fee and settles it; waiting to see costs the window in which treatment works best.

What if it was a children's ibuprofen liquid?

The same call applies. Liquids are absorbed quickly and it is easy to lose track of how much came out of the bottle. Take the bottle with you and note the concentration printed on it.
