Duke the Golden Retriever tried to sneak a rock past his owner, but the second she mentioned his favorite Greenies treat, he totally cracked and spit it out! The look on his face was pure guilt and determination—like he really thought he could pull it off. Apparently, this isn’t his first rock-rodeo either. People in the comments are convinced Duke’s got his owner trained to trade rocks for treats. Who knew rocks could be dog currency? #Pets #GoldenRetriever #DogTok
