Hi really sorry for late reply , not been on recently.
Good non slip mats are a must ,help me up harness especially if your furkid hates going to the toilet on a lead.
Barrier off all stairs and make ramps if needed.
Good physio , but remember to keep them as calm as possible after surgery.
Mine needs sedatives or she reinjures herself.
Make sure you have a good specialist,quiz them over their knowledge and success rate.
Hope it all goes well and I'll try to check in if you need more information
