Owney the Mail-Pouch Pooch by Mona Kerby is based on the true story of a remarkable terrier mix who became famous in the 1890’s. He was adopted by Albany, New York postal workers, and guarded the mail, only letting the men in blue uniforms near. One day he hopped on a train carrying mail across the country. The Albany men were sad, but a few months later Owney returned. He wanted to ride the train again! This time the railway postmen attached tags to Owney’s collar to show where he’d been. Soon he had so many, he had to wear a harness instead to hold them all! Owney traveled the world, guarding the mail on a steamship headed to Asia. This book is very well researched (the author even thanks a few Maryland librarians for helping get the facts straight) and features cute illustrations by Lynne Barasch.
