Magic bone.

When Sparky is left home alone, he bites his magic bone and winds up in Washington, DC! The US capital has statues, a monument that looks like a giant stick, and a big white house with a huge yard. His new dog friend says he's happy roaming the city without his family, but Sparky isn't so sure he feels the same. Can Sparky find a way to change his new friend's mind, and also find his way home?
