Ken, Thanks for the update on Emma. I had been wondering. Didn't know what had happened with her & didn't know why the other thread was locked. So glad to hear she is improving.
I'm still thinking it might be worth your time & your dad's money to see a veterinary acupuncturist. A friend of mine had a maltese with a similar problem and it was quickly relieved with acupuncture.
Here's a link to my vet's fact page:

Sometimes acupuncture can help solve a problem that would otherwise be considered chronic.
Praying her good days increase!
