Strudel, a homeless dachshund, loves listening to Jake read from Chief, Dog of the Old West at the animal shelter. When Jake decides to adopt him, Strudel vows to be as brave and loyal as Chief. But trying to fend off danger in his new home leads to trouble when Strudel makes mistakes, such as shredding a "rattlesnake" that is actually a garden hose. Despite Strudel's humorous miscalculations, his instincts are mostly correct. He's got a nose for who's really a member of his pack, and something about Mom's boyfriend, Arnie, just doesn't smell right.
