What Is Acetaminophen (Tylenol) and Why It Is Dangerous for Dogs

Acetaminophen, sold under brand names such as Tylenol, is a common over-the-counter pain reliever for people. Many dog owners wonder whether it is safe to share a human medicine cabinet with their pet. The short answer is that acetaminophen is not an NSAID, can lower fever and dull pain, but must never be given without veterinary guidance, and is flatly toxic to cats. Understanding how it works and where the real dangers lie helps you avoid a costly and potentially fatal mistake.
