My Lhasa went through that at age 3 1/2. it turned out that she had a herniated umbel (cant spell that word) cord. we had her spayed and she was alot happier and has not had any health problems since.
It was a hard decision for me as well, because i wanted to breed her onc, but as I look back I know that I did the right thing!
Good luck with whatever you decide to do.
