The veterinarian gets a knowing look in the eye, and suggests testing for Cushing’s disease. In a nutshell Cushing’s disease is a range of symptoms that occur because the body produces too much natural steroid.
Many dogs live with Cushing’s disease and cope with the niggling health issues for months or even years.
Smaller breeds, weighing less than 10kg, are more likely to develop Cushing’s than larger ones. When high doses of steroid-containing medication are given for a long time, there is a risk of inducing a man-made form of Cushing’s disease. However, the majority of cases suffer from the natural form of the disease where the body produces too much steroid.
Cushing’s disease develops when either the pituitary gland sends out a constant stream of requests (like having the pizzeria on auto-redial) or the adrenal gland goes into overdrive (the chef goes on a cooking marathon).
However, just like anything there are exceptions, and occasionally dogs with a large tumor (likely to have been growing for years) do show neurological signs such as head pressing, walking in circles, or seizures. Diagnosing Cushing’s disease can give your veterinarian a real headache because there is no single test that accurately diagnoses the condition.
A thirsty dog may drink more because he has kidney disease, diabetes, or one of many other problems, so your veterinarian runs screening blood tests to rule them out.
If your dog shows physical signs of Cushing’s disease, has cortisol in his urine, and suspicious hints on a general blood panel, then the next diagnostic step is to stimulate the pituitary and adrenal glands to see what happens. There are a variety of stimulation tests which can increase the suspicion of, or confirm a diagnosis of, Cushing’s disease. This works by destroying parts of the adrenal gland (a bit like shooting the pizza chef!) and came with some unpleasant side effects such as diarrhea, sickness, and life-threatening collapse. This technique was originally created to treat diabetic cats with a condition called acromegaly (where too much growth hormone is produced by the pituitary gland and it destabilises their diabetes) and the early work was done on cats. If all this has left you reeling, then remember that a dog with Cushing’s disease has months to years ahead of them.
Remember, there is no right or wrong decision when it comes to whether to treat Cushing’s disease. The little dog on your left has Cushing's disease, one of many diseases we will discuss in this section of our website.


One of my canine patients is a much-loved Collie-cross dog that has Cushing’s syndrome and pseudomyotonia.
Pseudomyotonia is a very rare disorder affecting less than 1% of all dogs with Cushing’s syndrome. Muscle changes associated with pseudomyotonia include weakness, stiff and stilted gait, distal muscle wasting, and sometimes muscle enlargement. Most of the Cushing’s dogs that develop pseudomyotonia also have the more common clinical features seen in dogs with hyperadrenocorticism including polyuria, polydipsia, pot belly, hepatomegaly, and hair loss. With spontaneous (endogenous) hyperadrenocorticism, myotonic signs generally partially improve with effective mitotane or trilostane therapy. Braund KG, Dillon AR, Mikeal RL: Subclinical myopathy associated with hyperadrenocorticism in the dog. Swinney GR, Foster SF, Church DB, Malik R: Myotonia associated with hyperadrenocorticism in two dogs.
The condition has much in common with aging because it progresses slowly and gradually erodes quality of life. However, a small percentage develop more serious signs such as circling or head pressing, with a few dogs dying suddenly from blood clots on the lung.
In her younger days Poppy was a whizz at fly-ball, but lately she preferred to watch the other dogs rather than take part. This signals that Poppy knew she needed to go but couldn’t hold on (incontinent dogs are unaware of the leakage).
Typically, this happens when a pet takes steroids (such as prednisolone or dexamethasone) to treat a condition such as cancer, inflammatory bowel disease, or itchy skin. With this in mind it is important that your veterinarian discusses the implications of long term steroid therapy before starting treatment.
Indeed some dogs had tumors up to 1cm across with no signs other than Cushing’s disease. Whilst Cushing’s cannot be diagnosed on a general blood profile, there may be strong hints pointing in this direction, such as high levels of alkaline phosphatase resulting from tissue damaged by excessive steroid.
One unfortunate complication of Cushing’s disease is high blood pressure, which may affect four out of every five cases.
You could potentially do more harm than good if you start your dog on Vetoryl but decline the monitoring that goes with it, so think very carefully before starting therapy.


In dogs the main risks are sudden onset blindness (caused by the retina detaching from the back of the eye), a stroke, or blood clot lodging in the lungs. Pippa Elliott (MRCVS)DescriptionThis is the complete dog owners guide to Cushing's Disease in dogs. I really would like to learn more about the connection between these diseases but have not had much luck! Muscle spasms may be elicited when a muscle belly is tapped gently with a percussion hammer. That said, it is an extremely rare clinical feature of Cushing’s syndrome, and the cause is not at all clear. I've divided the posts into 3 types: (1) my insights into specific endocrine issues, (2) Q & A posts that deal with questions I've gotten from veterinarians, and (3) reviews of current endocrine publications (with my comments and "insights").
If steroid is given continuously for several weeks the body may undergo the changes associated with Cushing’s disease.
Indeed, if it is essential your pet takes steroids, then there are methods of dosing (such as giving on alternating days) which can reduce the risk of Cushing’s disease.
For this reason, adrenalectomy (removing the adrenal gland) is best done at a specialist center with 24-hour intensive care facilities. This is possible because the pituitary gland sits at the base of the brain, with only a thin shelf of bone between it and back of the throat.
If surgery is top of your list, then referral to an internal medicine specialist, preferably one who works hand-in-hand with a neurosurgeon is essential. The relaxation of the involved muscle(s) are delayed and associated with persistent, repetitive electrical activity. I personally have not seen such a case, since these dogs do not have any underlying endocrine disease. However, others have suggested that this disease is not a simple consequence of Cushing’s syndrome but is a full-fledged disease in itself (see paper by Siliart et al in reference list).
This sounds off putting, but with proper specialist care most patients overcome these complications and do very well.
