Hi, I know you said that gripper socks wouldn’t work, but I just wanted to comment on that. I have a 12 year old standard poodle with fairly bad arthritis who kept slipping and falling on the hardwood floors in our new house. Very sad to watch. He is quite smart and figures things out quickly, and as you said we were sure he’d never accept the socks. Since they’re pretty cheap, I decided to give them a try just to see, and surprisingly he kept them on the very first time! He walked around a bit and seemed to get it that they made it so much easier for him. We’ve been using them since and I ordered several more pairs. I’d just suggest before you go to the trouble and expense, give them a try. For around $15 it’s worth a shot. Maybe your dog will be smart enough to see the benefit too, since she is also a very intelligent breed. We tried a couple of kinds and these have worked best for us.
