Cushing's Disease in Dogs: Know the Signs Before It's Too Late
Know the Signs • Catch It Early • Love Them Longer
In loving memory of Parce
This post is dedicated to one of my most beloved clients. Parce, you were one of the good ones. Forever in our hearts.
I am writing this one from the heart.
One of my most beloved clients passed away from Cushing's Disease. His name was Parce, a sweet, squishy English Bulldog who wore his little sweater like a gentleman and looked up at you with those big, soulful eyes every single time you walked through the door. He was one of the good ones. And losing him reminded me why this work matters so much.
Cushing's Disease is sneaky. It looks like aging. It looks like a dog just slowing down. And by the time most families realize something is really wrong, precious time has already been lost.
This post is for every dog parent who loves their dog the way Parce's family loved him. Read it. Share it. It could make all the difference.
What Is Cushing's Disease?
Cushing's Disease, also called hyperadrenocorticism, happens when a dog's body produces too much cortisol over a long period of time. Cortisol is a normal hormone that helps the body manage stress, inflammation, and metabolism. But when levels stay elevated for too long, it starts quietly damaging almost every system in the body.
It affects the skin, muscles, liver, immune system, gut, and metabolism. And because the symptoms come on slowly, many dogs go undiagnosed for months or even years. It can look just like normal aging, which is exactly why so many families miss it until it is too late.
7 Signs to Watch For
These signs are easy to dismiss as "just getting older" but they are not normal aging. If your dog is showing several of these at the same time, please call your vet right away.
Drinking and peeing a lot more than usual
One of the earliest and most consistent signs. If your dog is emptying their water bowl constantly or having accidents in the house, pay attention.
Always hungry, never satisfied
Cushing's increases appetite significantly. A dog who used to be a picky eater may suddenly act like they are starving all the time.
Panting even when it's cool
Excessive panting without exercise or heat is a red flag. Many owners chalk this up to anxiety, but it can be a sign of hormonal imbalance.
A pot-bellied appearance
The abdomen becomes enlarged and rounded even if the dog has not gained weight. Cortisol redistributes fat to the belly and weakens the abdominal muscles.
Thinning coat or hair loss
Symmetrical hair loss on both sides of the body is a classic Cushing's sign. The coat may also become dry, dull, or thin overall.
Skin infections that keep coming back
Chronic cortisol suppresses the immune system, making dogs prone to recurring skin and ear infections that never seem to fully clear up.
Lethargy and muscle loss
Dogs often seem tired, move slowly, and lose muscle mass over time, especially in the legs and back end. This is frequently mistaken for aging.
If your dog is showing several of these signs at the same time, call your vet and ask specifically about Cushing's Disease. Do not wait.
How Is Cushing's Disease Managed?
The good news is that Cushing's Disease is treatable, and many dogs go on to live comfortable, happy lives after diagnosis. The key is catching it early and staying consistent with care.
Veterinary Treatment
Medications like trilostane (Vetoryl) or mitotane are commonly prescribed to help regulate cortisol production. These medications require careful monitoring, including regular bloodwork, to make sure cortisol levels stay in a safe range. Routine checkups are not optional with Cushing's. They are essential.
Supportive Care at Home
Medication is only part of the picture. What you do at home every single day makes a real difference.
Fresh whole food
A nutrient-rich, minimally processed diet supports the liver, skin, and immune system. High-quality protein helps maintain muscle mass.
Omega-3 fatty acids
Help with inflammation, skin health, cognitive function, and heart health. Many vets recommend fish oil as a daily supplement.
Liver support
Chronic cortisol puts real strain on the liver. Supplements like milk thistle may help support liver function. Always check with your vet first.
Gut health
Supporting the microbiome helps the immune system and reduces the risk of recurring skin and ear infections.
Gentle movement
Short, calm activity helps preserve muscle mass and keeps the mind engaged. A gentle daily routine is enough.
Calm daily routine
Consistency in feeding times and schedules helps the body regulate better. Low stress makes a real difference for dogs with Cushing's.
How Long Can Dogs Live With Cushing's Disease?
With proper treatment and consistent care, many dogs live 2 to 4 years after diagnosis and often much longer. The prognosis depends on the cause, how early it was caught, and how well it is managed.
Early detection is everything. The sooner you catch it, the more options you have and the better quality of life your dog can enjoy. Do not wait on symptoms. If something feels off, trust your gut and call your vet.

Parce did not get enough time. But his story is going to help other dogs get more of it. That is the best way I know how to honor him.
