Sugar did not have LS, but some other kind of back end weakness. I've forgotten the details of how my vet described it. She was 3 months short of 12 yrs when it suddenly got Very Bad. Short term, she was on pred, which helped. She was already taking Metacam for arthritis, but we switched to Tramadol so she could have pain meds with the pred. I also started her on acupuncture regularly, which was a huge help. She got an Adequan shot, which really helped the first time, not so much the second time, so we didn't do it again. Her "long term" treatment was Tramadol as needed and acupuncture, which kept her in pretty good shape for 7 months. She passed away from acute kidney failure related to the heavy doses of heart meds she had been on for several years.
I am very much in favor of acupuncture!
