No, it is not safe to give your dog ibuprofen. Even a small dose can cause stomach ulcers and kidney damage, because dogs are far more sensitive to it than people. If your dog has eaten any, call your vet straight away, and ask them for pain relief made for dogs instead.
Ibuprofen is a staple in most medicine cabinets, for headaches and sore joints. That makes it an easy mistake when your dog seems to be in pain. But no amount of ibuprofen is safe for a dog, whatever their size. It is genuinely bad for dogs, not just a little risky.
Why is ibuprofen unsafe for dogs?
Because it strips away the stomach's protection and cuts blood flow to the kidneys. Ibuprofen is a non-steroidal anti-inflammatory drug, or NSAID. It blocks enzymes called COX. In people that eases pain. Dogs are much more sensitive to the effect, so the same action can cause severe damage.
- Stomach ulcers: painful sores and internal bleeding.
- Kidney injury: reduced blood flow can lead to sudden kidney damage.
- Nervous system effects: at high doses, tremors, seizures or coma.
A dose an adult takes for a headache can be dangerous for a medium-sized dog. The safety margin is far too narrow, which is why vets do not prescribe ibuprofen for dogs.
Myth: a tiny bit of ibuprofen is fine for a big dog. It is not. Dogs vary in how they react, and even a large dog can develop stomach ulcers from a dose that seems small.
Can I give my dog Nurofen or other brands?
No. Nurofen is simply a brand name for ibuprofen. Whether it says Nurofen, Advil or a supermarket own brand, the active ingredient is the same and so is the risk.
That applies to every form:
- Tablets and capsules: the most common source of poisoning.
- Liquids: often sweetened, which can make them more tempting to dogs.
- Gels and creams: a dog licking the skin where gel was applied can swallow a harmful amount.
There is no safe over-the-counter painkiller for dogs in your own medicine cabinet. If your dog is limping or showing signs of arthritis, see your vet.
What are the symptoms of ibuprofen toxicity in dogs?
The early signs are vomiting, diarrhoea and tummy pain, and they can progress to bleeding and kidney damage. What you see depends on how much was eaten and the size of your dog. The early signs are easy to mistake for a simple upset stomach.
- Vomiting: sometimes with fresh blood, or looking like coffee grounds.
- Diarrhoea: it may turn black and tarry, which can mean bleeding.
- Tummy pain: a hunched back, or not wanting to be touched.
- Loss of appetite: refusing food is common.
- Drinking and weeing more: possible early signs of kidney trouble.
- Pale gums: this may mean blood loss.
If your dog suddenly vomits or has changes in stool, check whether any tablets have gone missing. Our guide to sensitive stomachs in dogs covers other causes of tummy upsets, but never assume when medicine could be involved.
What should I do if my dog ate ibuprofen?
Call your vet or an out-of-hours clinic immediately, even if your dog seems fine. Do not wait for symptoms. Kidney damage can be hard to reverse once it shows.
- Remove the source: make sure your dog cannot eat any more.
- Call your vet: your daytime practice or the nearest emergency clinic.
- Do not try to make your dog sick: only a vet should decide that.
- Bring the packet: your vet needs the strength and how many may be gone.
Your vet may contact the Veterinary Poisons Information Service (VPIS), which supports UK vets managing poisoning cases like this.
How do vets treat ibuprofen poisoning?
There is no antidote, so treatment focuses on removing the drug and protecting the organs. That is why acting fast matters so much.
- Decontamination: if the tablets were swallowed recently, your vet may empty the stomach and give activated charcoal to bind the drug.
- Fluids into a vein: a drip supports blood flow to the kidneys.
- Stomach protection: medicines to protect the stomach lining and reduce acid.
- Monitoring: repeat blood tests to check the kidneys and red blood cells.
Early treatment makes a big difference. Delays raise the risk of serious complications, so never wait and see.
What can I give my dog for pain instead of ibuprofen?
Only pain relief prescribed by your vet. The dog equivalent of ibuprofen is a canine NSAID such as meloxicam or carprofen, made and licensed for dogs and dosed for your dog's weight. Your vet will check your dog is suitable before prescribing one.
For long-term stiffness, management goes beyond medicine. Weight control, steady exercise and joint support all help. If cold weather makes things worse, our guide to dog joint pain in winter has practical tips.
As an MRCVS-registered vet, I would also look beyond basic glucosamine. Many UK supplements contain only one or two actives, which does not reflect how complex joint health is. That is why I formulated Juno Daily to combine glucosamine and chondroitin with omega-3s and spirulina. Our page on Juno Daily for joints lists every amount. It supports joints over time, but it never replaces pain relief for a dog in pain.
Are dogs with sensitive stomachs at higher risk?
Yes. Ibuprofen is so harmful partly because of its effect on the gut, so dogs with existing digestive problems may be at even greater risk of ulcers.
For these dogs, everyday gut support matters even more. Juno Daily includes slippery elm, which helps soothe the gut, and Calsporin® Bacillus velezensis at 2 billion CFU per scoop, a spore-forming probiotic that survives stomach acid. Neither is a treatment for poisoning. If you are not sure what support your dog needs, the Juno supplement quiz is a sensible first step before you buy anything.
How can I prevent accidental ibuprofen poisoning?
Store all medicines out of reach, because most poisonings are accidents. Dogs are scavengers and will chew through boxes, foil and bottles.
- Store high: keep medicines in a high, closed cupboard, not on bedside tables.
- Secure bags: never leave handbags with tablets on the floor.
- Pick up dropped pills: find them straight away.
- Tell guests: ask visitors to keep their bags and medicines out of reach.
Older dogs who are confused or unsteady need extra care at home, and our senior dog care tips cover a safer home.
Keep your own painkillers locked away, and let your vet handle your dog's pain. For gentle daily support for joints and gut alongside your vet's plan, Juno Daily is an easy place to start.
Frequently asked questions
My dog ate ibuprofen and seems fine. Is that OK?
Not necessarily. Stomach ulcers and kidney damage can take a day or more to show, so a dog can seem well at first. Call your vet now, with the packet to hand, rather than waiting for signs.
My dog ate one 200mg ibuprofen. Will they be okay?
It depends on your dog's size. For a small dog, one tablet may be enough to cause ulcers and kidney injury. For a larger dog it can still irritate the stomach. Call your vet whatever the size.
What is the toxic dose of ibuprofen for dogs?
Stomach problems can start at fairly low doses, and kidney injury at higher ones. Sensitivity varies between dogs and there is no safe home dose, so vets treat any ingestion seriously.
Is paracetamol (Tylenol) safer than ibuprofen for dogs?
Vets do sometimes prescribe paracetamol for dogs in specific, controlled situations, but the wrong dose can be toxic, and it is unsafe for some dogs. Never give human paracetamol at home without your vet's instructions.
Can I give my dog aspirin for pain?
It is not recommended. Aspirin is an older NSAID with a relatively high risk of side effects in dogs. Modern dog-specific pain relief is safer and more effective.
How long does it take for ibuprofen to damage a dog's kidneys?
Kidney injury can begin within the first day, but obvious signs of kidney failure may not appear for several days. That is why treatment in the first few hours matters so much.
Can I give my dog children's ibuprofen?
No. Children's Nurofen and similar liquids are still ibuprofen, just at a lower strength. Some also contain sweeteners or other ingredients that are unsafe for dogs.
Can ibuprofen gel hurt my dog?
Yes. If your dog licks gel from your skin, or it is put on the dog, they can swallow enough to cause the same problems as a tablet. Cover the area or keep your dog away until the gel is absorbed.
