If you’re anything like me, every little change in your dog’s behavior sends up a red flag. A little extra panting? Strange. That bloated belly? Concerning. Drinking half the water bowl in one sitting? Not normal.
These might be symptoms of something called Cushing’s Disease in Dogs, a disease most dog parents have never even heard of until it’s happening to their beloved pet. So, let’s get down to brass tacks in plain English, dog lover to dog lover.
What Is Cushing’s Disease, Anyway?
Cushing’s Disease in Dogs (or hyperadrenocorticism, if you’re fancy) occurs when a dog’s body overproduces cortisol, the stress hormone. Cortisol is great for such things as metabolism and immune response, but too much for an extended period of time can begin to break down the body, and that’s where issues start.
So, What Should You Look Out For?
Cushing’s disease sneaks up on you slowly, so you may attribute the symptoms to getting older or just acting normally at first. But these are some things that could be signs of a problem:
- All that drinking and peeing way more than usual
- A never-stop-eating pup (way more than usual!)
- That blowfish, round “potbelly” appearance
- Hair loss or bald patches
- Laziness or not wanting to play
- Thin skin or lots of skin infections
- Excessive panting even when it’s not hot outside
Not every dog will show all of these signs, but if you’re seeing several at once, it’s worth a conversation with your vet.
What Causes It?
Most of the time, Cushing’s disease results from a tiny benign tumor on the pituitary gland (in the brain) that interferes with hormone messages. Less frequently, it’s due to an adrenal gland tumor (near the kidneys). And occasionally, it occurs when a dog has received long-term steroids (such as prednisone).
Diagnosing It: Not Always Easy
Your veterinarian may begin with simple blood and urine work, and if they suspect Cushing’s, they’ll probably perform one of the following:
- ACTH stimulation test
- Low-dose dexamethasone suppression test
- Ultrasound to examine the adrenal glands
It may take some patience and time to come to a diagnosis, but it’ll be worth it.
Good News: It’s Treatable!
Once you know what you’re working with, there are things to can control it.
- The most typical medication is Trilostane (Vetoryl), which assists in managing cortisol levels.
- In a few instances, surgery can be used (particularly in the event of an adrenal tumor).
- If your dog has iatrogenic Cushing’s (due to steroid medications), your veterinarian will assist you in gradually reducing the meds.
Cushing’s Disease in Dogs is an ongoing disease, not one that completely subsides, but through proper treatment and frequent checks, most dogs enjoy healthy, comfortable lifestyles.
Real Talk: Living with a Dog Who Has Cushing’s
Treating Cushing’s disease isn’t always simple, it can involve dosing daily meds, having regular blood work, and keeping an eye on your pup. But here’s the good news: once treatment begins to have an effect, most dogs brighten up. Their energy level picks up. The drinking and panting settle down. You begin to catch glimpses of the playful pup you recall.
And isn’t that worth everything?
Cushing’s Disease in Dogs (FAQs)
Cushing’s disease (hyperadrenocorticism) is a condition where a dog’s adrenal glands produce too much cortisol, a hormone that helps regulate metabolism, stress response, and immune function. Too much cortisol over time can lead to serious health issues.
With proper treatment, many dogs live for 2–4 years or more after diagnosis. Quality of life can be good with ongoing care and monitoring.
Not directly, but it can cause discomfort due to symptoms like skin infections, muscle weakness, and fatigue. Proper treatment significantly reduces discomfort and improves well-being.
There’s no way to prevent naturally occurring Cushing’s, but cautious use of steroids can prevent iatrogenic Cushing’s. Regular check-ups and early detection are your best tools.
Schedule a visit with your veterinarian. Bring a list of symptoms and any changes you’ve noticed in your dog’s behavior, appetite, or appearance. Early diagnosis and treatment are key.
Final Thoughts
If something does not feel “right” with your dog, particularly if they are middle-aged or older, don’t brush off those little warning signs. Trust your instincts. Cushing’s disease is more prevalent than you probably realize, and the earlier you catch it, the better.
You know your dog best. When they are not themselves, it is perfectly fine to ask questions, demand answers, and fight for their care. After all, they would do the same for you.
