Our cocker spaniel is 14 this year. She has recently been diagnosed with Cushing's. She showed all the signs, ie. drinking lots, excessive panting, shivering (on occasions), begging for food (which she had never done previously) and stealing food from bags! At first we just put it down to general old age and being 'a bit naughty'. The symptoms were very gradual and she still was enjoying a good quality of life. After ruling out diabetes, further tests confirmed the Cushing's. The vet was not in favour of prescribing the usual treatment as it can have pretty bad side effects (one of them being sudden death!). However, the vet found, whilst carrying out kidney tests, that she also had a water infection. She was put on a course of antibiotics and since then she's like a new dog! She still has the Cushing's, but the symptoms have improved. She doesn't drink to excess and her panting is back to that of a normal dog. She could have another couple of good years in her! But if the symptoms return and they making her unhappy, we have decided not to give her the treatment and will do the selfless thing when the time comes. Post back on here to let us know how yours get on.
