I have a couple ideas that worked for Maggie.

When she first had her amp I had wood laminate floors in the kitchen and dining area.  I had a couple of rugs, but for a small dog there was lots of space in between.

This one is probably only practical for small or medium dogs: I used the non-skid padding you buy to go under rugs.  It is pretty cheap and you can cut it into what ever size you need.  I actually made trails all over the rooms for Mag because she was so tentative on the floor.  She diligently followed the trails when ever she traversed the kitchen or dining room. When she got stronger and got her balance back I was able to get rid of the trails.  I have a couple of extra rugs in the kitchen, and now she goes from rug to rug.  (I also replaced the laminate with tile, that was for me not her though).

Last fall Mag started slipping a lot again on the tile floor.  Actually that is what led me to this site- I was  looking for some 3 legged dog non skid ideas.  What solved the problem this time was just some grooming.  I now trim the fur around her toes and pads, and use Musher's Secret to keep her pads soft- both of which give her better traction.

Out back I have a deck I built out of Timber Teck- one of those ' fake wood' materials.  Mag does OK on it, but was slipping coming up the one stair on each end.  I built the stairs for her- extra wide and only about 6″ high.  I got a couple of cheap outdoor rugs (about $2.50 each) and put them on the stairs.  She will not come up the stair unless she sees her rug there.

We have carpet runners in the kitchen and down the hallway to help Trouble on our tile floor.  She pretty much sticks to her pathway.  It isn't the prettiest solution, but it's worth it for her to be able to confidently move about the house.
