What Makes Ibuprofen (Advil, Motrin) Dangerous to Dogs?
Ibuprofen (sold as Advil, Motrin, and generics) is one of the most common over-the-counter medications that poison dogs. Dogs are much more sensitive to NSAIDs than humans. A single 200 mg tablet can cause stomach ulcers in a small dog, and higher doses can lead to kidney failure. Dogs may find and chew through bottles, making accidental overdose common.

When to See the Vet
Seek veterinary care for any ibuprofen ingestion in dogs. GI ulceration can occur at doses as low as 25 mg/kg, and kidney damage at 100 mg/kg. A single 200 mg tablet is a concern for dogs under 20 lbs.
Prognosis
Good with prompt decontamination and GI protectant therapy. Delayed cases involving kidney failure or gastric perforation carry a more guarded prognosis.

Frequently Asked Questions
- How much ibuprofen is toxic to a dog?
- GI ulceration can occur at 25 mg/kg, kidney failure at 100 mg/kg, and seizures/death at 400 mg/kg. For a 20 lb (9 kg) dog, a single 200 mg tablet is above the GI toxicity threshold. Always use our toxin checker to calculate the exact risk.
- Can I give my dog ibuprofen for pain?
- No. Never give human NSAIDs to dogs without veterinary guidance. Dogs metabolize ibuprofen differently and are much more susceptible to side effects. Veterinarian-prescribed alternatives like carprofen (Rimadyl) or meloxicam are much safer.
- What about acetaminophen (Tylenol) for dogs?
- Acetaminophen is also toxic to dogs, particularly to their liver and red blood cells. It is even more dangerous for cats. Never give any human pain medication to pets without consulting a veterinarian first.
