Introduction to Cushing’s Disease in Dogs

Cushing’s disease, also known as hyperadrenocorticism, is a hormonal disorder that affects dogs. It occurs when the dog’s body produces too much cortisol, a steroid hormone produced by the adrenal gland. This excess cortisol can cause a range of physical symptoms in dogs, which can be difficult to diagnose. Cushing’s disease is more common in older dogs, and certain breeds such as poodles, terriers, and dachshunds are more susceptible to the condition.

Increased Thirst and Urination

One of the most common symptoms of Cushing’s disease in dogs is increased thirst and urination. The excess cortisol hormone can cause the dog’s kidneys to work harder and produce more urine, leading to frequent urination and increased thirst. This can result in accidents in the house, as the dog may not be able to hold their urine for long periods of time. In addition, the dog may need to drink more water to compensate for the increased urine production, leading to a constant need for access to water sources.

Hair Loss and Thin Skin

Cushing’s disease in dogs can also cause hair loss and thin skin. The excess cortisol can cause the dog’s skin to become thin and fragile, leading to hair loss and bald patches. This can be particularly noticeable on the dog’s belly, where the skin may become almost transparent. In addition, the dog’s coat may become thin and dull, and may not regrow as quickly as it should. The skin may also be more prone to infections and irritations, which can exacerbate the hair loss and thin skin.
