Good news. I'm happy to hear it and know that Layla is improving.
we'll play around with the dosage amount
I hope you mean the vet will do that. Prednisone (and all cortisone preps) need to be weaned down slowly to lower and lower doses and not stopped abruptly after being given for several weeks or months. That's because it takes the adrenal glands time to get back to their normal level of cortisol production.
