I found in short research a lot of German Shepherds, the DCAU had a Black Dane mix, and one bulldog.
This League Of Super-Pets movie confuses me. There have been enough animated and comic versions of the various superhero pets that they shouldn’t screw this up. I think someone either had a script about superanimals ready and went to DC because they couldn’t get it made otherwise or they just wanted to use their favorite animals instead of the established breeds and pets. It’s just a continuation of what’s wrong with the adaptations of their owners.
