Lost: Black Lab mix with blue collar near Friday Harbor

I lost my Milo yesterday around 6:30 pm near the Friday Harbor ferry terminal and along Spring Street. He's a 2-year-old black Labrador mix, about 60 pounds, with a blue nylon collar and an orange ID tag that says MILO. He has a small heart-shaped white patch on his chest and a little notch in his left ear. If you see him, he's usually friendly but a bit shy with new people, and he sometimes limps on his right paw after a long walk. This dog is my walking companion and it's really stressful not knowing where he is—I'd be incredibly grateful to get him back.
