Doggy dog is an example of an eggcorn in linguistics (“a misheard word or phrase”). The original saying (dog-eat-dog) is misheard or spoken so quickly, it sounds like something else.
Over the course of 6 weeks, I developed a storyboard, exploratory sketches, and two style frames based on Bob the Dog’s journey.
