Tan lab mix with blue collar, Buddy missing

I lost my dog yesterday around 3pm near the Cajundome on Cajundome Blvd, just off University Ave in Lafayette. He's a tan Labrador mix, about 40 pounds, with a blue collar and a small silver tag that reads 'Buddy', plus a tiny white patch on his chest. He can be reactive to squirrels and tends to pull on the leash, so he bolted when we passed a busy intersection and I lost sight of him toward the library area by the Cajundome. He's deeply loved by my 9-year-old daughter, and I’d really appreciate any help—he's microchipped; reach me through the app to arrange a return.
