Best way to hide the wire running on the floor

[MetalHead84]

I was wondering what is the best way to hide the speaker wire that are running on the floor (no carpet) and that will be safe enough for kids or pets running around.
There is no wall near 1 of my 2 surround, so the wire will be directly on the floor and I don't want my dog to chew the wire, or my futur kids to fall on the wire.

Edit : And there is no basement, so that's not an option to run the wire from the basement
