Cushing disease in dogs: Managing symptoms
Cushing disease in dogs also known as hyperadrenocorticism, is a common endocrine disorder that can affect dogs of all ages and breeds. Lets understand details of Cushing’s disease, including its causes, symptoms, diagnosis, and available treatment options.

what is Cushings disease ?
Cushings disease also known as cushing syndrome. It occurs when the adrenal glands produce excessive cortisol hormone in the body. They are of two types.
- Pituitary-dependent Cushing’s disease
- Adrenal-dependent Cushing’s disease
In pituitary-dependent Cushing’s disease, a tumor in the pituitary gland leads to an overproduction of adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands to produce excess cortisol. Adrenal-dependent Cushing’s disease occurs when a tumor develops within the adrenal glands, resulting in the excessive production of cortisol directly. Excessive cortisol production can have various effects on the pet’s body and overall health.
Symptoms of cushing disease in dogs
It is important to note that the symptoms and severity of Cushing’s disease can vary among individual pets. If you suspect that your pet may have elevated cortisol levels or Cushing’s disease, it is crucial to consult with a veterinarian for proper diagnosis and appropriate treatment options. You need to examin a dog for symptoms of Cushing’s disease.
Increased thirst and urination
Excess cortisol can interfere with the normal regulation of water balance in the body, leading to increased thirst and urination in pets.
Weight gain
Cortisol can affect metabolism and promote the accumulation of fat, leading to weight gain, particularly in the abdominal area. Pets with Cushing’s disease often develop a rounded, pot-bellied appearance.
Hair loss and thinning skin
Elevated cortisol levels can cause changes in the pet’s skin and coat. Dogs with Cushing’s disease may experience hair loss, thinning of the skin, and the development of easily bruised or thin skin.
Muscle weakness
Excessive cortisol can contribute to muscle weakness and wasting in pets. They may exhibit a decrease in muscle mass and strength, leading to reduced activity levels and exercise intolerance.
Increased susceptibility to infections
Cortisol can suppress the immune system, making pets more vulnerable to infections. Dogs with Cushing’s disease may experience recurrent skin infections, urinary tract infections, or other infections that are slow to heal.
Panting and respiratory changes
Pets with Cushing’s disease may exhibit increased panting due to the effects of cortisol on respiration. They may also have difficulty breathing or show signs of respiratory distress in severe cases.
Behavioral changes
Changes in cortisol levels can impact a pet’s behavior and mood. Dogs with Cushing’s disease may display increased restlessness, irritability, anxiety, or changes in appetite and sleep patterns.
Cushing syndrome treatments
Diagnosing cushing disease in dogs can be complex. Veterinary expertise is crucial in interpreting the test results and determining the most appropriate treatment plan for the pet.
Diagnosing Cushing’s disease in dogs involves a series of tests like
Medical history and physical examination
The veterinarian will gather a detailed medical history from the pet owner, including any observed symptoms or changes in behavior.
Blood tests
Blood tests are conducted to check cortisol levels and assess the functioning of the adrenal glands.
ACTH stimulation test
This test measures the response of the adrenal glands to synthetic adrenocorticotropic hormone (ACTH). Blood test, before and after administering ACTH, this will help to determine the cortisol levels and adrenal gland response.
Low-dose dexamethasone suppression test (LDDST)
Synthetic glucocorticoid/dexamethasone is administered to suppress the production of cortisol. Blood are dont to understand cortisol levels and adrenal gland response.
Baseline cortisol level test
Blood test is also dont to understand the baseline cortisol levels in the pet. High lvls of cortisol levels can help understand the underlying condition.
Urine tests
Urine samples may be collected to measure cortisol levels or to assess cortisol-to-creatinine ratios. High cortisol levels in urine can support the diagnosis of Cushing’s disease.
Imaging techniques
Ultrasound or Radiography isrecommended to visualize the adrenal glands and detect any tumors or abnormalities. Imaging can help differentiate between pituitary-dependent and adrenal-dependent Cushing’s disease.
Additional tests
Depending on the results of initial tests or to further investigate specific cases, additional diagnostic procedures such as endogenous ACTH measurement, high-dose dexamethasone suppression test, or adrenal gland imaging with CT or MRI may be performed.
Once a diagnosis is confirmed, treatment options for Cushing’s disease in dogs can include medication, surgery, or a combination of both, depending on the underlying cause. Medications like mitotane or trilostane are commonly prescribed to manage the production of cortisol. In cases where a tumor is present, surgical removal may be necessary.
It is important to work closely with your veterinarian to develop a tailored treatment plan for your dog. Regular monitoring and follow-up appointments will be necessary to assess the response to treatment and make any necessary adjustments.
Cushing’s disease is a complex hormonal disorder that can affect dogs. By understanding the causes, recognizing the symptoms, and seeking appropriate veterinary care, you can effectively manage Cushing’s disease in your pet and improve their overall quality of life.
