Hi Dori

I don’t have an answer for you about the supplement, but the rear leg tremor is fairly common for dogs with spinal problems. Over time they develop weakness and muscle wasting because of the damage to the spine. What are the chances you can swim her when the weather gets better? It’s the best exercise for these things. The swing in her gait may also be her spinal issues rather than hips, or she may have damaged her hips compensating for her spine.
