Me again! Zuzu drops like that too, always has. We did a couple of things recently that seem to have helped (she does not need TPLO and if she needed the surgery, we'd do it without hesitation...she's sore and swollen but not torn enough to benefit from surgical repair).
- ortho bed - we got one orthopedic bed (XL) from LLBean. We also got an eggcrate shape, full size, 4" thick memory foam mattress topper from Overstock.com (about $80, free shipping) and an extra LLBean XL cover. Fits perfectly folded in half. So now each dog has an ortho bed and neither seems to have a preference.
- Adequan injections - she got one/week for 4 weeks and now is on 1/month.
- Trixsyn supplement - it is supposed to lubricate joints. She gets this in addition to her Cosequin DS.
- Switched from Rimadyl to Metacam - Metacam seems safer, fewer side effects, is once/day and she seems to do really well on it. She was on Rimadyl twice/day and I could see it "wearing off" before her next dose.
- Acupuncture/Chiropractic - it may seem silly to some but thousands of years of Chinese medicine can't be all wrong can it? Plus I'm a believer in Chiropractic as I've had it myself and it made a huge difference for me. Again, once/week for 4 weeks now we're going every 2 weeks with a goal of being at once/month by April. She is significantly more solid, structurally speaking, than she was when we started, and her adjustments are holding better from one appointment to the next.
Good luck with everything, I know how heartbreaking it is to see them suffer. I hope the surgery will fix everything - but if he doesn't need it please know there are other therapies that can help him get better!
