Tan Labrador mix dog with blue collar

I lost my tan Labrador mix yesterday around 3pm near the Riverside Park entrance at Main Street and Oak Avenue in La Salle Co. He is about 60 pounds, with a white chest patch and a small scar on his right ear, and he is wearing a bright blue collar with a bone-shaped tag that reads 'Milo'. Milo is incredibly friendly, and he is never far from my side; he is a gift to me since we adopted him. This loss hits hard; he has sentimental value and I really need him back. If you spot him, please contact me; I hope to bring him home soon.
