Border collie mix with blue collar missing.

I lost my border collie mix yesterday around 3pm near the Mashpee Commons parking lot on Route 130 in Mashpee, Cape Cod. She’s about 50 pounds, mostly black with tan markings, and wears a bright blue reflective collar with a silver name tag that reads 'Maggie.' She has a small white patch on her chest and a tiny scar on her left hind leg. She bolted when I paused to help a couple with a stroller near the seafood shack, and the seagulls by the water scared her. This dog means the world to me—she’s my hiking buddy and helped me through a rough year. If you spot her, message me here and I’ll head over right away.
