Lost gold locket with delicate floral design and two small pictures, lost while walking a dog in Logan Park.

I lost my gold locket while walking my dog in Logan Park last Saturday. It has a delicate floral design on the front and the inside holds two small pictures, one of my grandmother and one of my late dog. It fell off during our walk, and I've retraced my steps multiple times without any luck. I'm very attached to it and would appreciate any help in getting it back.
