Can dogs eat ibuprofen (advil, motrin)?
If your dog has just eaten ibuprofen (advil, motrin)
Do this now
- Call your vet or ASPCA (888) 426-4435 immediately
- Bring the bottle to the vet — exact strength and count matter
- Do NOT induce vomiting without vet instruction
- Time is critical — activated charcoal is most effective within 1-2 hours
- Treatment usually includes IV fluids, GI protectants, and monitoring kidney function
- Watch for: vomiting (often bloody), black tarry stool, lethargy, decreased urination, seizures
What your vet will want to know
Have this information ready when you call:
- Exact strength (200, 400, 600, 800 mg)
- Number of tablets ingested
- Any children's liquid ingested (mL + strength)
- Time of ingestion
- Your dog's weight
The full picture
Ibuprofen is an NSAID (non-steroidal anti-inflammatory drug) widely used in humans but highly toxic to dogs. The therapeutic index (gap between helpful dose and toxic dose) is extremely narrow in dogs. Toxicity mechanism: ibuprofen inhibits an enzyme called COX-1 that protects the stomach lining and maintains kidney blood flow. In dogs, this inhibition happens at doses proportionally similar to human doses — but dogs metabolize the drug 2-3x slower, so damage accumulates. Result: severe stomach ulcers (can perforate within 48 hours), acute kidney injury (can become permanent), and at very high doses, liver damage and neurological signs. As little as one 200 mg tablet can cause ulcers in a 25 lb dog. One extra-strength 600 mg prescription tablet can cause kidney failure. Never give ibuprofen to a dog. Ever.

Check if vomiting is safe →Risks to watch for
- Stomach ulcers (often within 24 hours)
- Intestinal perforation
- Acute kidney injury (often irreversible)
- Liver damage at higher doses
- Neurological signs at very high doses (coma, seizures)
- GI bleeding (bloody vomit or stool)
Symptom timeline
Symptoms typically progress in stages. Knowing what to expect helps you act fast:
- 1–4 hours Early: vomiting (sometimes bloody), abdominal pain, refusing food
- 4–24 hours GI signs worsen; black tarry stool (melena) — sign of stomach bleeding
- 24–72 hours Kidney injury: decreased urination, lethargy, increased thirst
- 72+ hours Severe: complete kidney failure, liver damage, seizures
Breed-specific warnings
- Small dogs can be fatally poisoned by single regular-strength tablet (200 mg).
- Senior dogs or those with pre-existing kidney issues: any dose potentially catastrophic.
Safe portion size
None. No circumstance justifies giving ibuprofen to a dog.
Safer alternatives
- Prescription dog-specific NSAIDs (always prescribed by your vet)
- Never human NSAIDs
- For acute injury pain: call your vet for vet-approved options
Common questions
My dog ate one Advil — is it an emergency?
Yes, essentially always. Even one 200 mg tablet can cause stomach ulcers in a medium-sized dog. Smaller dogs face immediate kidney risk. Call your vet immediately.
Are there any NSAIDs that are safe for dogs?
YES — but only prescription dog-specific NSAIDs: Rimadyl (carprofen), Galliprant (grapiprant), Metacam (meloxicam), Previcox (firocoxib). These are formulated and dosed specifically for canine metabolism. Never human NSAIDs.
What's the antidote for ibuprofen?
No specific antidote exists. Treatment is supportive: IV fluids to protect kidneys, GI protectants (omeprazole, sucralfate) for ulcers, blood transfusion if GI bleeding is severe. 48-72 hour hospitalization common. Cost: $1,500-$5,000+.
How is ibuprofen different from Tylenol in terms of risk?
Different damage patterns. Ibuprofen: GI ulcers + kidney damage. Tylenol: liver damage + blood oxygen issues. Both are emergencies; neither is safe for dogs. Aleve (naproxen) is similar to ibuprofen but longer-acting, making it arguably worse.
