Which game show host ended his shows by asking people to have their pets spayed or neutered?

Bob Barker

Answer: At the end of every Price Is Right episode, longtime game show host Bob Barker burned these words into viewers’ minds: “Help control the pet population. Have your pets spayed or neutered.” When his wife Dorothy Jo died, Barker became an advocate for animal rights and of animal-rights activism. As for Barker’s signature line on TV, it didn’t stop when the 88-year-old retired in 2007. Since then, host Drew Carey has faithfully delivered the plea morning after morning at the end of every show.
