Lost golden retriever named Charlie last seen near Sombrero Beach wearing a blue collar in the Florida Keys.

I lost my golden retriever, Charlie, while we were taking a walk near Sombrero Beach in the Florida Keys. He’s friendly and was last seen wearing a blue collar with my contact info. I was distracted by some local wildlife, and when I turned around, he was gone. If anyone has seen him, please let me know. I’m really worried about him!
