Dog Drawing By Breathed Berkeley

Several newspapers chose not to run the August 26, 2007, Opus cartoon because it might offend Muslims.
On October 6, 2008, Breathed announced plans to discontinue all work on comic strips with the final Opus strip to run on November 2, 2008. Breathed plans to focus on writing children's books. Breathed explained that he felt that the United States was going to face "tough times", and that he wanted to end the saga of his most memorable character "on a lighter note".
The last Opus comic strip appeared on schedule, but in what may be a comic first the final panel required an online link. The final panel the strip showed Opus sleeping peacefully in the bed depicted in the classic children's book, Goodnight Moon. Unfortunately, this panel was available only online, and the Humane Society page that displayed it no longer exists.
Breathed said that he had no regrets in leaving political cartooning, as he believes the atmosphere became too bitter for him to make quality cartoons.
