But now that she is compromised, I guess she can't handle the additional stress on her system. I am sick to my stomach thinking that I have been giving her something that has been making her worse. Of course my vet never suggested anything about NOT giving her this stuff. In fact, she already has shown exposure anaplasmosis (testing shows positive) so it seemed even more important to give her these with all the tick bourne diseases around. Damned if you do and damned if you don't. Can't do anything right anymore.
