Could this still be made today?

This film, which Paramount deemed too controversial for release, is about an unnamed German Shepherd that is trained by his previous, racist owner to attack black people.

After a young woman almost runs the dog over, she adopts him without realizing this important fact. The dog goes on a African-American killing spree and the woman's boyfriend, who is black, tries to cure him of his trainer-caused mental defect.

In the end, the dog is accidentally trained to start killing white people instead of black people and is shot. The movie rights were bought by NBC for an edited TV broadcast but they canceled the plan when the NAACP, advertisers and viewers were outraged. In fairness, the movie was intended as an examination of racism as a mental disease, but that message was lost.
