Missing Dog Koa: Reward! Tan Lab/Shepherd Mix

Koa is a neutered 4year old lab and shepherd mix. He was about 65 lbs we he went chasing a rabbit and disappeared. There are a lot of warehouses in the area. Safeway distribution, Amazon, Medline etc. We haven’t had any sightings and we wonder if a truck driver picked him up. We are desperate to find him and offering REWARD. My son is disabled and he was his good buddy! He has a scar ( from surgery) on his left side. Mostly tan with black muzzle!
