"Dog? Where?" Scooby looked around curiously, as if not knowing what he really was. Likely because the gang never really treated him like a dog, at least, they treated him a lot like they did Shaggy.
Shaggy laughed and took a large bite of his impossibly big sandwich, expecting Cher to keep going. She didn't come closer, and just sort of did that girly thing they all did when seeing something they deemed 'adorable.' He was sure Scooby wouldn't object if it meant getting a treat or a good scratch behind the ears. He was more interested in the massive sandwich, deciding after a minute that it needed more peppers.
