Hercules is Smithers' Yorkshire Terrier. He is only mentioned once , so very little is known about him. According to Smithers, the name is a joke because he is "Kinda tiny." When Mr. Burns asks Smithers what he did over the weekend, he says that he "Caught up on his laundry, wrote a letter to his mother, and he took Hercules out for a clip."
