Harry Horse's Last... Books

Grandfather and Roo, a remarkable dog with strong views and a short attention span, are off to Australia, on an expedition to find long-lost Uncle Vincent, who ran away to seek his fortune years ago. Roo is worried about Australia being upside down, but that turns out to be the least of their problems. After a tricky flight the intrepid explorers land in Sidney, Australia—not Sydney, as it turns out—and must advance up the Snakey River to Gold Town. Grandfather and Roo endure blistering heat, a rebellious camel, and disreputable kangaroos, as they head off on foot to find the Gold Field, last known home of Uncle Vincent.
