Many cartoon dogs are anthropomorphized to some extent. They can walk on two legs, wear clothes, and even have jobs or hobbies. This gives them more relatable qualities and allows for more interesting storylines.
Cartoon dogs usually have distinct personalities. Some might be brave like Clifford the Big Red Dog, who is not only large but also very courageous and always ready to help his friends. Others could be a bit clumsy but still endearing.
Most cartoon dogs are cute and friendly. They are often depicted as loyal companions, like how Snoopy is to Charlie Brown in Peanuts. They can also be funny, with exaggerated expressions and behaviors to make the audience laugh.
