Brown and white border collie mix lost near Main Street

I lost my dog, a medium-sized brown and white border collie mix, yesterday around 3pm near the Walmart on West Main Street in Dothan. He’s about 40 pounds, with a brown patch over his left eye and a white blaze down his nose, and he wears a red nylon collar with a small brass tag that reads Milo. He has a tiny star-shaped white patch on his chest and one ear that flops when he runs. He’s usually friendly, but can be wary of strangers until he relaxes. It means a lot to me—he’s a rescue and has sentimental value, and I’m really hoping to bring him home safely if you’ve seen him.
