Ours seem to be used to our hard wood...they do slide out sometimes...we also have many area rugs so there isn't a ton of exposed floor. They slide more on our tiled floor...mostly when they are tired.
We have wood and tile floors but like Leslie, lots of throw rugs. No problem for Tanner in fact one of his favorite things is to have you throw his ball, he runs and when he hits a rug he slides....loves it
we have all wood floors and the dogs have no problem with slipping. Fred slipped about a little when we first got him, but not anymore. We jsut took the carpet off the stairs too, and the dogs have done just fine. I was worried that i would need to put another stair runner down, but fred has been doing fine on the wood. I am glad about that, since it is a lot easier to sweep the stairs then having to vacuum them.
Wait a minute!!!!!!!!!!!!!!!I'm hung up on the fact that some of you have throw rugs and your doods haven't torn them up. Tucker and Frankie chew on them and have ruined a few. These guys can't even have a dog bed, they have destroyed them as well.
We have all tile floors except in the bedrooms and we have some throw rugs rugs at various high traffic areas. Ozzie usually "spins his wheels" getting up to sprinting speed on the bare floor, then uses a rug like a baseball player sliding into home plate.
So... we're constantly "unscrunching" the rugs. The positive thing is he was initially chewing the smaller rugs' end tassels and corners but lost interest quickly.
