Ibuprofen Toxicity Calculator for Dogs

GI ulcers develop at doses of 50 mg/kg, kidney failure at 150+ mg/kg, and seizures or CNS toxicity at 400+ mg/kg. To put this in perspective: a single 200 mg tablet can be dangerous for a small dog under 10 lbs (4.5 kg). Because dogs are far more sensitive to NSAIDs than humans, even a single OTC dose can cause serious harm. Never assume a "small" amount is safe — always calculate the mg/kg dose and contact your vet.

Call your veterinarian or ASPCA Poison Control at (888) 426-4435 immediately. Bring the original bottle and an accurate pill count to the vet — they need the exact mg/kg ingested to determine the right treatment. Do NOT induce vomiting without professional guidance, as ibuprofen can be absorbed quickly and vomiting may cause additional complications. Treatment may include IV fluids for kidney protection, stomach protectants (misoprostol, sucralfate), activated charcoal, and 48-72 hour hospitalization with bloodwork monitoring.

Only use vet-prescribed NSAIDs formulated specifically for dogs: carprofen (Rimadyl), meloxicam (Metacam), galliprant, and grapiprant are common examples. These are metabolized differently than human NSAIDs and have been safety-tested for canine use. NEVER give human ibuprofen (Advil, Motrin), naproxen (Aleve), or aspirin to your dog without explicit veterinary instruction — the canine therapeutic window for these drugs is dangerously narrow, and overdose can cause irreversible kidney or liver damage. For pain management, always consult your vet for a dog-appropriate medication and dose.
