Hi Kathy,
The collection of internal medical complaints suggest either Yi Guan Jian or Xiao Chai Hu Tang as treatments. If you've been tonifying her, and the paralysis appeared anyway, then maybe we need to try the Shao Yang approach. A deep wiry pulse would fit that.
The other possibility, given the response to your acupuncture points, might be a wind invasion secondary to Blood deficiency. That would call for Du Huo Ji Sheng Tang. If you saw improvements on the tonics before this happened, that might be the next step for the dog.
If you saw no benefits of tonics, I'd wonder about Xiao Chai Hu Tang, or Shen Tong Zhu Yu Tang. The latter doesn't often work in dogs, but fits the points.
Hopefully that is enough information to suss out what to try next
