Wow, KayIS, thanks for the great info!! I'm going to do a bunch of reading on the site you linked me and head into the vet's with an armload of info. I'm not too optomistic about our local vet, but I'm sure going to try. And I'll have to see if I can get the methelene blue here. I've never even heard about it.
I really appreciate your help with this, and I can't wait to hear your report. I'll report as well after I talk to the vet and see if I can get any of this stuff.

Diane
