Kirsten, when Luna is on an antibiotic, do you ever give her yogurt or acidphilus(??)to keep her tummy and the rest of the GI tract happy?? The antibiotic, besides getting rid if the infection, also destroys the " good" bugs in the gut. The yogurt or acidphilus help maintain the "good" bugs. I will open up a capsule of the acidphilus and mix it with the wet food. Usually have no problems and it gets in with the food. Human doctors are starting to recommend this for humans, too. Will say prayers that Luna will be her OLD self soon!!!
