BoxerPhoebe

People's experiences on testing for suspected Cushings disease , how is this done ? 9 yr old boxer . She is happy in herself , recently developed lots of dark patches then started loosing hair , she has had an excessive thirst for a long time . At the vet appointment we eventually got a course of prednisolone , as they don't know what it is . That has helped mildly , looking for advice with a course of action.
