Found beagle mix dog with navy collar

I found a beagle mix dog yesterday around 3pm wandering near the Chautauqua Library on Main Street, just past the coffee shop. She's a medium-sized beagle, about 25 pounds, with a tri-color coat—white chest, brown patches, and a black saddle—and a nervous wag when I spoke to her. She’s wearing a navy blue nylon collar with a small heart-shaped tag that reads 'Ella' and a tiny white star on her chest. There’s a slight limp in her right hind leg, which may help identify her. I brought her to the shelter on Park Street here in Chautauqua to help get her home. If anyone recognizes her, describe the tag name or the distinctive features to tell her apart.
