Please help if you see her (my dog)

Hi All

I was walking my new rescue mostly beagle (we think she’s part chihuahua) in the North End and there was a loud noise and she bolted, pulling her leash out of my hand. Her name is Maggie. She is much faster than I am, and the sound of the leash dragging behind her kept scaring her so she kept running. We have no idea where she is. The leash is blue. Her tags have all of our information on her. If anyone finds her please call. We will offer a reward. Thank you so much for your help, we are panicked as we already have fallen in love with her. She is a sweetheart who just loves love! She came from the rural South and is 16 lbs and about 7 years old. Thank you!!
