I think my garbage was stolen. Should I freak out now?

I went to throw away some garbage this morning, and when I opened my garbage can, there was almost nothing in there. I looked at the ground, and a blinds box we threw away was scattered on the lawn. I picked it up and took the garbage to the curb, and noticed pieces of a foam noodle floaty thing were scattered on the lawn by my car, and further inside my lawn behind my fence. Now, I could have sworn I had more garbage in there than I saw, but I am not sure. Earlier in the week I also threw out some grease too, so maybe it was just a dog? Should I be concerned? My credit is poor, so it’s not like they could do much in that regards if it indeed was an identity thief, but is there something I should do, or just chalk it up to a hungry dog?
