Understanding these behavioral changes is crucial for providing the best care and support for dogs with Cushing’s disease.

Cushing’s disease, also known as hyperadrenocorticism, occurs when the adrenal glands produce excessive amounts of cortisol. This excess cortisol can lead to a range of physical and behavioral symptoms in dogs. Common physical symptoms include increased thirst and urination, weight gain, panting, and skin infections. However, it’s the behavioral changes that often catch dog owners off guard.

Dogs with Cushing’s disease may exhibit a variety of behavioral changes that can affect their overall temperament and quality of life. These changes can include:

1. Increased Restlessness and Anxiety

Due to elevated cortisol levels, dogs with Cushing’s disease may experience increased restlessness and anxiety. They may appear more agitated, have difficulty settling down, and exhibit signs of nervousness or pacing.

2. Altered Sleep Patterns

Cushing’s disease can disrupt a dog’s normal sleep patterns. Dogs may experience difficulty falling asleep or staying asleep, leading to increased nighttime activity and daytime drowsiness.

3. Changes in Social Interactions

Some dogs with Cushing’s disease may exhibit changes in their social interactions. They may become more irritable or aggressive towards other animals or people, or they may withdraw from social interactions altogether.

4. Increased Vocalization

Excessive barking or vocalization is another behavioral change commonly observed in dogs with Cushing’s disease. Dogs may bark more frequently, seemingly without reason or provocation.

5. Decreased Interest in Activities

Cushing’s disease can cause dogs to lose interest in activities they once enjoyed. They may become lethargic, less playful, and show a general lack of enthusiasm.

While weight gain is a physical symptom of Cushing’s disease, it can also manifest as increased food-related behaviors. Dogs may become more demanding for food, steal food from countertops or trash bins, or exhibit obsessive behaviors around mealtime.

7. House Soiling

In some cases, dogs with Cushing’s disease may experience difficulty controlling their bladder or bowels, leading to house soiling accidents.
