My 8 year old redbone coon hound has cushings, yes, we went thru all the test.. It is in his pituitary, but didn't look enlarged. He is 95 lbs, will be 9 in Nov. Has been neutered. The symptoms are food obsessed,going thru trash, tearing open anything he might find looking for food, frequent urinating ( not too bad ) doesn't want to go on walks, doesn't wag his tail anymore, doesn't drink a lot of water. No bulging stomach, no skin infections, I think I caught it early.
