I'm not sure. It could potentially refer to a comic depicting oneself at a party with lots of dogs, but without more context, it's difficult to determine precisely.
To determine if you were a good girl dog in the comic, we need to look at your behavior and how it impacted the story. If you were friendly, obedient, and did positive things, chances are you were good.
Wild Dog is indeed based on a comic character. The creators drew elements from the comic to shape the concept and plot of the show. There might be some tweaks and adaptations for the screen, but the core roots are in the comic.
