What You Need to Know
Oreos contain cocoa powder giving them a theobromine content that poses toxicity risk especially to small dogs. A single Oreo is unlikely to cause serious toxicity in a large dog but the combination of theobromine, high sugar, and high fat makes them consistently unsuitable. Never give Oreos to dogs.
