Checking a dog's adrenal glands involves diagnostic blood tests to measure cortisol levels (ACTH stimulation or Low-Dose Dexamethasone Suppression tests) to check for Cushing's or Addison's disease, alongside imaging like ultrasound to visualize tumor size or structural changes. These tests are performed by veterinarians to evaluate how the glands respond to hormone stimulation or suppression.

What breed of dogs are prone to Cushing's disease?

Dogs prone to Cushing's disease (hyperadrenocorticism) are typically middle-aged to older, with smaller breeds like Poodles, Dachshunds, Yorkshire Terriers, Bichon Frises, and Terriers (Border, Jack Russell) being more susceptible, while German Shepherds and Boxers are also at higher risk, especially for adrenal-dependent forms, though it affects many breeds.

What are the symptoms of high cortisol levels in dogs?

The most common clinical signs are increased appetite, increased water consumption, and increased urination. The increased appetite is a direct result of elevated cortisol levels, which stimulate appetite. Lethargy (drowsiness or lack of activity) and a poor hair coat are also common in pets with hyperadrenocorticism.

What breeds of dogs need their glands expressed?

Breeds that commonly need regular anal gland expression are generally the smaller ones. For example, Chihuahuas, Shih Tzus, Toy Poodles, Bichon Frisés, Lhasa Apsos, and Cavalier King Charles Spaniels are frequently cited as needing help emptying their glands.

What happens if your dog doesn't get his glands expressed?

Are dogs with Cushing's always hungry?

Yes, an increased appetite (polyphagia) is a hallmark symptom of Cushing's disease in dogs, often appearing alongside excessive thirst (polydipsia) and urination (polyuria), as high cortisol levels directly stimulate hunger and affect metabolism. While not every dog will show extreme hunger, it's a very common sign, along with a pot-bellied appearance, thinning hair, skin issues, and lethargy, that warrants a vet visit. 

Is walking good for a dog with Cushing's disease?

How did my dog get Cushing's disease?

Cushing's disease (hyperadrenocorticism) in dogs is caused by prolonged exposure to excess cortisol, usually from a benign pituitary tumor (most common), a tumor on an adrenal gland, or prolonged use of steroid medications (iatrogenic Cushing's). The pituitary tumor overstimulates the adrenals, while an adrenal tumor produces cortisol directly; both lead to the body making too much cortisol, causing symptoms like increased thirst, urination, skin issues, and a pot-bellied appearance.
 

Do dogs with Cushing's disease poop a lot?

Typically, dogs with Cushing's disease experience excessive urine production and increased thirst. Diarrhea is not commonly associated with Cushing's.

Cushing's rarely appears in dogs under 6 years old, and the mean age is 8 to 12 years. Small breeds are more prone to the pituitary-dependent form, and medium to large breeds account for about half of the adrenal-dependent form. Some studies suggest females face more risk than males.

What other conditions mimic adrenal insufficiency?

Weakness, fatigue, myalgia and psychiatric symptoms are known to be both common and non-specific in patients with central adrenal insufficiency. Thus, central adrenal insufficiency is often misdiagnosed as depression and/or chronic anxiety disorder.
