Lost small brown Dachshund dog named Max with blue collar and tag at Lake of the Ozarks.

I lost my small brown Dachshund named Max while visiting the Lake of the Ozarks. He ran off after seeing a squirrel and I haven't been able to find him since last Saturday. He’s wearing a blue collar with a tag that has my phone number on it. If anyone has seen him, please let me know, I’m so worried!
