Brown and white beagle mix, lost by bayfront

I lost my brown and white beagle mix yesterday around 5:15pm. He's about 25 pounds, white chest, and a brown patch over his left eye. He’s wearing a red collar with a blue tag that has my name and phone number, and a tiny white scar behind his right ear. I last saw him near the American Bank Center on Staples Street by the Corpus Christi bayfront; he bolted when I stopped to grab a snack at the CVS. I’m really worried—he’s not just a dog, he's my walking buddy and this dog has sentimental value; any sighting helps a lot.
