I'm confused -- if his Cushings is managed, then he should no longer be peeing like crazy - that stops when the Cushing meds are titrated correctly. Diet doesn't manage Cushings at all, but it sounds like you're saying you're 'managing' Cushings w/ his diet....? All diet helps with in terms of Cushings is that it can help those dogs who are overweight as a result of UNmanaged or UNtreated Cushings.
What meds are you using for his Cushings?
