@lenaoflune Thanks! We did all the tests to diagnose Cushing's and the vet has prescribed it. We have an appointment to have his first dose and another blood test, then again in 7 and 14 days. The vet wants to start at a low dose and work up slowly to avoid problems. I sure hope it helps him.
@h8cloz That's the safest way to do it, yep, and what we did with our older dog that developed Cushing's. An overdose, especially in a smaller dog, can be very, very bad :/
