When Toby had cushings he drank lots like 7 litres of water a day and he was a llasha x poodle, he ate everything in site and his piddle looked like water no concentration in it. Cushings is over producing adrenal glands which is like cortisol. That is a very basic concept of it. I hope its nothing serious for your ole boy and they find something to help him soon. Sometimes I think vets think we are crazy but we know what is normal for our pets better then they do.Good luck...Jill
