Lost black Labrador retriever named Max near the park in downtown Kirksville, Missouri.

I lost my black Labrador retriever named Max while walking him near the park in downtown Kirksville yesterday afternoon. He slipped out of his collar when he saw a squirrel and ran off. Max is friendly but can be a bit skittish around strangers. If anyone has seen him or has any information, please contact me. He loves treats and is very playful.
