Brindle terrier mix, blue harness, white chest

Yesterday around 6pm, my brindle terrier Rex bolted from me when we were leaving a coffee shop near the Empire State Plaza on State Street in Albany. He’s about 40 pounds, short-haired with a white chest patch and a slightly bent left ear. He’s wearing a blue reflective harness and a blue name tag that says 'Rex' along with my phone number. He's really important to my family - my kids adore him and he has sentimental value because he was a gift from my late aunt. If anyone finds him, text me and we can meet up anywhere in Albany to pick him up.
