Lost dog: Black Lab mix with red collar

I lost my black Labrador mix, about 65 pounds, yesterday around 3pm near Lincoln Road in Miami Beach. He's got a shiny black coat with a small white patch on his chest, and a bright red collar with a blue bone-shaped tag. There’s a noticeable scar behind his right ear, and he tends to limp a little on his left hind leg after an old injury. He’s friendly once he knows you, but he can be wary of strangers, so he might back away at first. This dog means everything to me—he’s family and has a lot of sentimental value. If you’ve seen him or picked him up, please reach out; I’ll come to meet you anywhere in South Florida to bring him home.
