She broke out with the same rash a few days ago, and (stupidly) instead of taking her to the vet, I gave her the same dosage of
medicine that we had left over from the last time. I gave her 20mg in the morning, 20 in the evening, and then realized that I didn't have enough to complete the course for three weeks. I gave her an additional 20mg dose yesterday morning, and nothing this morning. My question is, what is the best way to wean her off the medicine without causing her harm?
