Cowboy Little and Cowboy Small love adventures with their horses Ned and Ted, their dogs Red and Fred, their pet fleas Itch and Scratch and their cattle Brawny Bull and Helen Heifer. When they chance upon old saddlebags filled with ancient Spanish coins and a strange map, they set out to solve the mystery. Along the way they face bandits, Indians and bats. The Children's Book review set the optimal age for this chapter book at 8-10, but it's a great read aloud book for ages 4 and up.
