Hello, We're dogsitting a rat terrier for a friend, and he ranaway. We lost him in a mountainous area (Santa Cruz Mountains in Calif.) that features vineyards, forest, and occasional subdivisions. I don't know too much about this breed's behavior and have little experience with dogs myself. The weather is sunny, relatively warm, but chilly at night. He was last seen in a subdivision at the bottom of a valley where there is a creek. Does anyone have any tips on where a Rat Terrier might go if he were lost? Will he stay on the move, or is he more likely to stay in one place. One person in the subdivision gave him water and food, but he ran off again. We have already placed craiglist ads, put up posters, and called animal control.
