Sadie is an older Lab, and sometimes her feet don't grip as they should on carpet. So when I found these rug grips I thought they were worth a try. We have a camper with throw rugs, but Sadie can't seem to walk on them without them slipping. A few minutes of time, I was able to but the Anit Curling Rug Grippers on the two big throw rugs, and put them back down. Now no matter how Sadie walk on them, they don't move, they stay put if I walk on them. they even stay put when my big grumpy hubby walks on them. He even likes how tight they stay down.
