A is for Alsatian

When a prize- winning yellow lab is stolen in Spain, Rodrigo and Samantha hit the road with a former shelter dog named Silver. The Alsatian's nose for Amarillo's scent leads the Dog Finders to North Africa and the eastern Mediterranean, in one adventure after another for the amateur detectives. In the end they encounter a miracle amidst the ruins of an ancient city. This story is also available as G is for German Shepherd.
