Hi Tessie and family, welcome. Hope you don't mind I moved your post here, it's a better place to help get your mobility questions answered.

You have our sympathies about the diagnosis. We know it's shocking but I'll bet you are already seeing signs that Tessie is feeling so much better without that bad leg. The sadness is probably due to the pain medications. What is she taking?

Sounds like you're super about her weight, which is awesome. Kudos!

The hardwood floors will indeed be slippery and like skating on ice for her. That doesn't change. You can help reduce the risk of spills and muscle strains by trimming fur between her paws. Boots are not recommended as a long-term indoor solution, since most of us humans will have a hard time getting into the habit of putting them on and taking them off every day.

Traction is key (click on the link for ideas). I know it really stinks to cover up those pretty floors ( we had to do it as well), but placing carpet runners throughout Tessie's favorite places in the home will go a long way to help avoid injury. Tripawds use their bodies in new ways and that means compensating with the remaining limbs. The result is the "Tripod" stance that doesn't make it easy to recover from sudden slips.

Hope this helps!
