Have you considered toe grips? They slide onto the dogs claw and help give them traction on hard floors, we used them on our old golden who had long claws and they really helped with the sliding they look simaler to claw caps for cats with the tip cut off. They don't need to be glued on eitherYou groom your dog yourself, don't you? Can you work on his toenails?
We're boarding a dog who had such poor mobility I think the owners were starting to wonder how long to let it go on. He was due for a bath, and I really worked at his nails with the dremel. They said when they picked him up, they noticed his mobility had improved so much. We've boarded him several times and I've noticed a huge improvement, too. We've been keeping on top of those nails and he still is arthritic with some aches and pains, but, the nubby-short nails have REALLY made a huge difference in how he's able to get around.
He has black nails and is a little antsy for me when I've tried to cut/dremel them, so they make me nervous. The groomer at the vet does a great job of keeping them short though.
