Lost black Labrador mix with red collar

I lost my dog Milo, a 2-year-old black Labrador mix, yesterday around 3pm. He's about 60 pounds, with a shiny coat and a distinctive white patch on his chest, plus a small scar on his right ear. He wears a bright red collar with a silver name tag that says Milo and my phone number, and he has a subtle limp in his left hind leg from a winter tumble. I was by the Clark Fork River trailhead behind the Wilma Theatre on Higgins Ave when he darted away; I miss him and really need him back. If you spot him around Missoula—near Bonner Park or the library—please text me. He’s friendly and my hiking buddy, and I’m really worried.
