Lost red adjustable dog harness and matching leash with dog's name stitched on near the brewpub at the beach in Cape Cod.

I lost my red dog harness and matching leash while walking my golden retriever on the beach in Cape Cod. We were near the brewpub when I realized I had taken it off for a quick dip in the water, and I must have left it behind. It's adjustable and has my dog's name stitched on it.
