Magic Bone : Go fetch!

"When Sparky's owner leaves him with no one to play with, Sparky decides to beat the boredom with a bite of his magic bone. He finds himself in Washington, DC, among statues, a monument that looks like a giant stick, and a big white house with a huge yard (that he isn't allowed to play in). His new dog friend says he's happy roaming the city without his family, but Sparky isn't so sure he feels the same. Tag along as Sparky explores the United States capital-- and tries not to get caught!" --from publisher's web site.
