Judge Richard Meen called CJ an "outstanding example of the breed," according to NPR.
Reserve best in show, a prize second only to best in show, went to a borzoi named Lucy, according to the Westminster Kennel Club.
CJ also beat out a German shepherd, shih tzu, Samoyed, Skye terrier and bulldog for his new title. According to the AP, it was his 18th overall best in show win.
The title didn't include any cash prize but instead “valuable breeding rights in the near future and a legacy in dogdom forever,” AP reported.
It was only the third time a German shorthaired pointer took the top prize, KTLA reported.
