Lost brown chihuahua with black stripes and a white muzzle.

Our small brown chihuahua mix who has black brindle-like stripes and a white muzzle was lost in the Marina/Cow Hollow District in San Francisco on 6/19/22. We believe that he was picked up by a young woman and likely given away. He is neutered, has a mole on the left side of his face and has long hind legs. If you know of or see a chihuahua who resembles ours, would you please contact me. We have been searching for him every day since he disappeared. Thank you.
