Will your dog be OK after eating Advil?

You should never give human medications to animals. Dogs in particular are very sensitive to the side effects of Advil (and Tylenol and Aleve and aspirin and every other pain reliever humans use) - one pill can be enough to cause a fatal stomach ulcer that kills your dog.

If you think your dog is in pain, you should take him to your veterinarian who can prescribe a safe pain reliever for you dog if he needs it.
