My 70 lb 12 year old golden retriever has a skin condition and was on
Prednisone last year for about three weeks. 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.
