Cindy, I had mentioned that they balance themselves with their tail, that was a good idea holding it up to see if she walked better that way. Hopefully it's just that her body isn't able to absorb the vitamins efficiently and once you find out the results of the blood work, you will have some answers as to what will help her. I know when Sabrina was having walking issues with her back legs, Tracie and I discussed that as they get older, they need to have some B vitamins supplemented to help them out. It did make a difference with Sabrina for a while.
