Dog is one of the two protagonists of the Nickelodeon animated series CatDog. Dog is the more happy-go-lucky and more naive of the two. He is also the source of clumsiness. He is extremely ambitious when Cat or any other character convinces him to take on a task, diving right into it with full force and energy. Dog is the typical loyal dog and is easily convinced. He will believe everything he is told. His attention span is very short and he is easily distracted by balls, garbage trucks, bones, food, and his overactive imagination. Because of his dysfunctional brain, Dog usually is the one who gets the pair into trouble. Not paying attention to Cat's warnings, his actions almost always end up with some severe consequences. Despite this, in many of the episodes, it is shown that Dog is usually the one that is more popular and athletic of the two, such as the episode when Cat and Dog both went back to school to complete Cat's last day of High School. Like Cat, Dog adores his brother and looks up to him no matter how many times Cat steers him into danger. Dog is the typical animal. He is often distracted with chasing shadows and chasing after tennis balls, and loves eating garabage. Much to Cat's dismay, he leaves a mess everywhere he goes. According to the series finale, Dog remembers what their parents were like "Mom's four eyes, Dad's slimy green skin." He is also 26. Dog's catchphrase is "Hi ho diggety," and he usually says this when he is excited about something.
