We have recently moved and our new house has hard wood floors (which I love) but my older dog is having such a hard time! -I have rugs down but he still is having a hard time! And yes I have tried dog booties!
I have no suggestions but I'm interested in hearing. I have a dog that is 12.5 years old and I have hardwood floors. For some reason though, she seems to prefer to lay on the hardwood as opposed to the area rug.

You can try this product. Also sold on Amazon where you can read the reviews first.
For a quick substutute, dip your dog's paws in a saucer of soft drink. Cola or uncola if you prefer. Let it dry to a tackiness that will help your dog's traction.
Depending on what kind of dog, too, make sure any overly long hair in between pads is clipped.
Your dog may simply have very dry footpads. A bit of moistening may help. Just use a hand cream. Of course, avoid the creams with slippery silicone. The tackier the better.
