cushings is a nasty disease. it originally was found in horses. it is somewhat common in k-9 . we lost both of our pomeraians to it they were litter mates . basically a cancer of the pituitary gland . very expensive treatment when issuing meds was suppose to handle with rubber gloves and pregnant women was not to handle at all . ironically our next door neighbor granddaughter contracted it during this time weight gain frequent urination and the outcome wasn’t good . this was about 5 years ago . hopefully some advances has been made
