I was going crazy. I passed out flyers to all neighbors and searched under every bush in the yard. Then I'd stand at the fence into neighbors' 3 acre field and call him. I didn't expect him to answer (or come to me) but it made me feel like I was doing something. And I have a 15 year oldchihuahua that gets out of a yard with 6' wooden privacy fence that we call Houdini.
