Ibuprofen and dogs — common questions

Can ibuprofen poison a dog?

Causes GI ulceration at low doses, kidney injury above ~100 mg/kg (dog), and CNS signs above ~300 mg/kg. Cats are far more sensitive. How serious it is depends on your dog's body weight and how much they ate — use the calculator above for the exact dose and a clear severity level.

How much ibuprofen does it take to harm a dog?

It depends on your dog's weight, how much they ate, and the exact form. Ibuprofen comes in different forms (200 mg tablet (each), 400 mg tablet (each), children's suspension (mg/g)) and the concentration varies between them, so the form matters as much as the amount. Enter the details above to get the dose in mg/kg and whether it lands in the low, moderate, high, or emergency range.
