Does URL depth / structure affect rankings?

Let's imagine my site is about dogs and I have content ready to launch, the only thing to be decided is the URL structure/depth and keyword orderin url.

Is there any advantage using same level urls or deeper ones? (Let me explain what I mean). Does keyword order in url have effect on rank?

Example:

Targeting: dog, dog treats, huge dog treats, smelly dog treats
animalyummy.tld/dog/
animalyummy.tld/dog/treats/
animalyummy.tld/dog/treats/huge/
animalyummy.tld/dog/treats/smelly/

VS

animalyummy.tld/dog/
animalyummy.tld/dog-treats/
animalyummy.tld/dog-treats-huge/
animalyummy.tld/dog-treats-smelly/

VS (order changed)

animalyummy.tld/dog/
animalyummy.tld/dog-treats/
animalyummy.tld/huge-dog-treats/
animalyummy.tld/smelly-dog-treats/
