Cushing’s disease in dogs is one of the most common health issues seen in older pets. It happens when a dog’s body produces too much cortisol, a hormone that helps manage stress, weight, and overall health. While some dogs exhibit mild signs, others display significant changes in their body and behavior. Understanding this illness is very important for pet parents who want their furry friends to stay healthy and happy.
Many owners first notice small changes, such as increased thirst or frequent urination. Over time, the symptoms of dog Cushing’s disease can affect daily life. Luckily, with the right care, many dogs live long and comfortable lives. In this article, we will look at what causes the problem, how to spot it, and the best ways to treat it.
What Is Cushing’s Disease in Dogs?
Cushing’s disease in dogs, also called hyperadrenocorticism, happens when the adrenal glands make too much cortisol. This hormone is useful in small amounts but harmful when it stays high for a long time.
There are two main types of dog Cushing’s disease:
- Pituitary-dependent Cushing’s disease: Caused by a small tumor in the brain’s pituitary gland.
- Adrenal-dependent Cushing’s disease: Caused by a tumor on one of the adrenal glands near the kidneys.
Both forms can lead to similar signs, but treatment may be different. Knowing the type is the first step to helping a dog live well with this condition.
Common Signs of Dog Cushing’s Disease
Most dogs show changes slowly, which makes the disease easy to miss in the early stages. Pet parents often think their dog is just getting older.
Typical symptoms of Cushing’s disease in dogs include:
- Drinking more water than usual
- Needing to urinate often
- Gaining weight or developing a pot-bellied look
- Eating more than before
- Losing hair or having thin skin
- Panting even when resting
Not every dog will have all these signs. Some dogs may only show one or two. That’s why paying close attention to behavior is so important.
Causes of Cushing’s Disease in Dogs
Dog Cushing’s disease can happen for different reasons. The main causes include:
- Pituitary gland tumor: This is the most common reason, found in about 80–85% of cases.
- Adrenal gland tumor: Less common, but it may require surgery if the tumor grows large.
- Long-term steroid use: Some dogs develop the condition after taking steroids for allergies or other problems.
Understanding the cause helps vets choose the right treatment plan. Without knowing the source, it is harder to manage the disease properly.
How Veterinarians Diagnose Dog Cushing’s Disease
Since the signs look like those of other illnesses, vets run several tests before making a diagnosis.
The most common tests for Cushing’s disease in dogs are:
- Blood tests to measure hormone levels
- Urine tests to check for high cortisol
- ACTH stimulation test shows how the body responds to hormones
- Ultrasound scans to find tumors on the adrenal glands
These tests take time and may be repeated. Accurate diagnosis is important to avoid giving the wrong treatment.
Treatment Options for Dog Cushing’s Disease
There is no single cure for dog Cushing’s disease, but there are treatments that help manage it. The right plan depends on the cause, the dog’s age, and overall health.
Common treatment methods include:
- Medications: Drugs like trilostane or mitotane help control cortisol levels.
- Surgery: If the cause is an adrenal tumor, surgery may remove it.
- Radiation therapy: In rare cases, pituitary tumors are treated with radiation.
Most dogs live comfortably with medicine and regular vet visits. Treatment is a lifelong commitment, but it helps dogs enjoy a better quality of life.
Daily Care for Dogs with Cushing’s Disease
Living with dog Cushing disease requires daily care and monitoring. Pet parents play a big role in keeping their pets stable.
Here are some helpful care tips:
- Give medicine on time every day as prescribed.
- Watch for side effects, such as loss of appetite or vomiting.
- Keep track of water intake and bathroom habits to notice changes early.
- Visit the vet regularly for checkups and blood tests.
Routine and patience are key. With the right support, many dogs can live many happy years after being diagnosed.
Possible Complications of Dog Cushing’s Disease
Even with treatment, some dogs may develop complications. These often come from the body’s long exposure to high cortisol.
Complications may include:
- Diabetes is caused by a hormone imbalance.
- High blood pressure leading to heart and kidney problems
- Blood clots that can become dangerous
- Infections due to a weaker immune system
By staying alert and working closely with a vet, many of these risks can be managed or reduced.
How Long Do Dogs with Cushing’s Disease Live?
One of the most common questions pet parents ask is how long a dog with Cushing’s disease can live. The answer depends on the type and how early it was diagnosed.
- With proper treatment, many dogs live two to four years after diagnosis.
- Some live longer if the disease is well managed.
- Dogs with untreated Cushing’s disease may face serious health problems within a year.
Quality of life is just as important as lifespan. Regular monitoring, proper care, and a loving home make a big difference.
Preventing Dog Cushing’s Disease
Not all cases of Cushing’s disease in dogs can be prevented, but there are ways to lower risks.
Prevention tips include:
- Avoiding unnecessary steroid use unless prescribed by a vet.
- Taking older dogs for regular checkups to catch signs early.
- Watching for changes in appetite, water drinking, or bathroom habits.
Early action gives the best chance of managing the disease well.
Supporting Dogs Emotionally and Physically
Dogs with Cushing’s disease need more than medical care. They also need emotional support. Changes in their body and energy can be confusing for them.
Ways to help include:
- Providing a calm routine to reduce stress.
- Gentle exercise suited to their energy level.
- Extra love and attention to keep their spirits high.
This balanced approach makes life better for both the dog and the owner.
Final Thoughts

The key things to remember are:
- Pay attention to the early signs of dog Cushing’s disease.
