As a dog owner, it’s natural to feel concerned when your pet’s behavior or physical condition changes. One health issue that can cause significant changes in your dog’s appearance and demeanor is Cushing’s disease. Also known as hyperadrenocorticism, this condition occurs when your dog’s body produces too much cortisol, a hormone that plays a crucial role in various bodily functions. In this article, we’ll delve into the world of Cushing’s disease, exploring its causes, symptoms, diagnosis, and treatment options. By the end of this guide, you’ll be well-equipped to identify the signs of Cushing’s disease in your dog and take the necessary steps to ensure their health and well-being.
Understanding Cushing’s Disease
Cushing’s disease is a common endocrine disorder that affects dogs of all ages and breeds. It’s estimated that approximately 1-2% of dogs will develop Cushing’s disease at some point in their lives. The condition is caused by an overproduction of cortisol, which can be triggered by a variety of factors, including benign tumors on the pituitary gland, adrenal gland tumors, or long-term use of corticosteroid medications. When cortisol levels become too high, it can lead to a range of symptoms that can significantly impact your dog’s quality of life.
Symptoms of Cushing’s Disease
Identifying the symptoms of Cushing’s disease is crucial for early diagnosis and treatment. Some common signs of the condition include:
Increased thirst and urination, leading to accidents in the house or excessive water consumption
Weight gain, particularly in the abdominal area, resulting in a characteristic “pot-bellied” appearance
Thin, fragile skin that’s prone to tearing and bruising
Poor coat condition, including excessive shedding or dry, dull fur
Increased appetite, leading to overeating or food obsession
Fatigue, lethargy, or decreased exercise tolerance
Panting, even in cooler temperatures or at rest
Recurring skin infections or hot spots
Hair loss, particularly on the flanks, tail, and face
It’s essential to note that these symptoms can be subtle at first and may develop gradually over time. If you’ve noticed any of these changes in your dog, it’s crucial to consult with your veterinarian to rule out other potential causes and determine the best course of action.

What is Cushing’s disease in dogs, and how common is it?
Cushing’s disease, also known as hyperadrenocorticism, is a common endocrine disorder that affects dogs. It is characterized by an overproduction of cortisol, a hormone that plays a crucial role in the body’s response to stress, regulating blood sugar levels, and aiding in the metabolism of fat, protein, and carbohydrates. The disease is often caused by a benign tumor on the pituitary gland, which is located at the base of the brain, or by a tumor on the adrenal gland, which is located near the kidneys.
The incidence of Cushing’s disease in dogs is relatively high, with some estimates suggesting that it affects up to 2% of dogs over the age of 10. Certain breeds, such as Poodles, Dachshunds, and Boxers, are more prone to developing the disease due to genetic factors. Additionally, dogs that are overweight or have a family history of the disease are also at increased risk. If left untreated, Cushing’s disease can lead to a range of serious health complications, including diabetes, kidney disease, and heart disease, making early detection and treatment essential for managing the condition and improving the dog’s quality of life.
What are the common symptoms of Cushing’s disease in dogs?
The symptoms of Cushing’s disease in dogs can be varied and non-specific, making diagnosis challenging. Some common signs of the disease include increased thirst and urination, weight gain, particularly in the abdominal area, and a pot-bellied appearance. Dogs with Cushing’s disease may also exhibit changes in their skin and coat, such as thinning of the skin, poor wound healing, and a dull, dry coat. Additionally, some dogs may experience increased appetite, panting, and restlessness, while others may show signs of lethargy, depression, and anxiety.
As the disease progresses, dogs may develop more severe symptoms, including hair loss, particularly on the torso, and the appearance of purple stretch marks on the abdomen. They may also experience muscle weakness, which can lead to difficulties walking or exercising. In some cases, dogs with Cushing’s disease may develop secondary health complications, such as diabetes, kidney disease, or heart disease, which can further exacerbate their symptoms. If you suspect that your dog is showing signs of Cushing’s disease, it is essential to consult with a veterinarian, who can perform diagnostic tests to confirm the presence of the disease and develop an effective treatment plan.
How is Cushing’s disease diagnosed in dogs?
Diagnosing Cushing’s disease in dogs typically involves a combination of physical examination, medical history, laboratory tests, and imaging studies. The veterinarian will start by performing a thorough physical examination, taking note of any signs of illness, such as weight gain, thinning skin, or poor coat condition.
