Medium tan lab mix with blue collar missing

I lost my dog, a medium-sized tan and white lab mix named Rex. He was last seen yesterday around 3pm near the Jefferson Theatre on College Street in Beaumont. He wears a light-blue nylon collar with a bone-shaped tag that says 'Rex' and my number. He's usually friendly, but can be wary of new people, especially around loud noises. He has a white patch on his chest and a small scar on his right hind leg, plus a slightly droopy left ear. He's part of our little family and it would mean the world to get him back. If you've seen him in the Beaumont / Port Arthur area, reach out with any info. Thanks for reading and keeping an eye out.
