Cushing’s Disease in Dogs: Key Signs and Symptoms to Watch For

Cushing’s disease, also known as hyperadrenocorticism, is a common endocrine disorder in dogs caused by an overproduction of cortisol. This hormone imbalance can lead to a variety of health issues if left untreated. Understanding the key signs and symptoms is crucial for early detection and effective management.

What is Cushing’s Disease?

Cushing’s disease occurs when the adrenal glands produce excessive cortisol, often due to a tumor on the pituitary gland or adrenal glands themselves. Cortisol is vital for regulating metabolism, immune response, and stress, but too much can disrupt normal bodily functions.

Key Signs and Symptoms to Watch For

Recognizing the symptoms early can help pet owners seek veterinary care promptly. Common signs include:

Symptom	Description
Increased Thirst (Polydipsia)	Dogs drink more water than usual, often leading to frequent urination.
Increased Urination (Polyuria)	Excessive urination due to increased water intake and kidney effects.
Increased Appetite (Polyphagia)	Dogs may show a heightened hunger and eat more than normal.
Abdominal Enlargement (Pot-bellied appearance)	Fat redistribution and muscle weakness cause a swollen belly.
Hair Loss (Alopecia)	Thinning or loss of hair, often symmetrical, without itching.
Skin Changes	Thinning skin, bruising, and slow wound healing are common.
Lethargy and Weakness	Dogs may appear tired, less active, and weak.
Panting	Excessive panting even without exercise or heat exposure.

Causes and Risk Factors

Pituitary Tumors: The most common cause, leading to increased ACTH and cortisol production.
Adrenal Tumors: Less common but directly increase cortisol secretion.
Iatrogenic Cushing’s: Resulting from prolonged corticosteroid use.
Breed Predisposition: Breeds like Poodles, Dachshunds, and Boxers are more susceptible.

Diagnosis

Veterinarians use a combination of physical exams, blood tests, urine analysis, and imaging (ultrasound or CT scans) to confirm Cushing’s disease.

Treatment Options

Medication: Drugs like trilostane or mitotane to control cortisol production.
Surgery: Removal of adrenal tumors if present.
Monitoring: Regular check-ups to adjust treatment and manage side effects.
