I use the one from Natures Farmacy (yes it's spelled like that!). It last me a long time even with daily use. It comes in a powder and even my picky dog likes it. I pick it up at dog shows but you can also order online.
Joanne, I had a basenji with CUPS. Autoimmune disorder, and much in the line, so sure as heck genetic.

@DebraDownSouth:
Any vet who is not aware of the guidelines and titres isn't one who stays informed enough to be my vet. Any vet who PRETENDS they don't know and tries to push unnecessary vaccine– ditto.
Thanks for the post, will share in other dog groups.
