Video at above link provides details of how the Obamas are finding him a "little crazy".
Details on the book from NYT:
He has already been the subject of obsessive news media coverage, and now he will be the subject of a children’s book. Bo the Portuguese water dog who recently became the first presidential pet in the Obama White House, is the star of “Bo, America’s Commander in Leash,” expected in stores by the end of the month. Mascot Books, a small independent publisher in Herndon, Va., specializing in titles based on university and school mascots, is rushing the book out to capitalize on the fervor surrounding the Obamas’ new dog. “Bo” is written by Naren Aryal, a founder of Mascot Books, and illustrated by Danny Moore, one of its employees. Mr. Aryal said he and Mr. Moore had been working on the project for about two months, leaving space for pictures of the dog, once it was chosen. Mr. Aryal said the Obamas’ two daughters aren’t named in the book because he wanted to protect their privacy.and more via Denver Post.
