I came upon this in a blog i some times visit. I've not had time to try 
and verify  but thought it might be of interest to this list.
Excerpt from blog post below.  link here

"In the spirit of sharing useful, if bizarre, information: Someone on 
the corgi listserv to which we belong recently found their corgi 
paralyzed at the rear. The vets worked on the dog for about 24 hours, 
whereupon he suddenly recovered. They could find nothing wrong.

Someone else on the list asked if the dog could have eaten any macadamia 
nuts - and indeed he had. Turns out that macadamias can cause temporary 
paralysis in dogs. So, readers with canines, take care of the macadamias."
