The Last Dog On Earth

The Last Dog on Earth is a 2003 young adult novel written by Daniel Ehrenhaft. It follows Logan, a lonely 14-year-old boy who adopts a dog from an animal shelter and names her Jack. The pair's relationship is soon threatened by an incurable prion disease spreading across the nation. Infected dogs become unnaturally violent and bloodthirsty, culminating in the deaths of several people. As public fear heightens and the government intervenes to control the outbreak, Logan struggles to reform his life and remain with Jack.

The Last Dog on Earth largely focuses on the impact of disease and both public and governmental panic. Society is ravaged by fear over the epidemic, endangering Logan and Jack despite the two being uninfected. Additionally, the novel presents a coming of age story in which Logan, a troubled youth, matures through his relationship with Jack, his only friend.

Despite 17th Street Productions holding the rights to The Last Dog on Earth, Dell Publishing gained permission to publish it. The company released the novel in hardcover in 2003 and in paperback in 2004. Throughout 2009, the book was published on various e-book readers, including the Nook, Kindle, and several Apple Inc. products. The Last Dog on Earth was a winner of the Texas Lone Star Reading List and recognized by YALSA on a 2006 book list for young adults. The novel garnered mixed feedback from critics, who generally felt that the plot held appeal, but that Ehrenhaft tended to rely on coincidence.
