Addison’s disease (hypoadrenocorticism) in dogs is rising, primarily driven by genetic predisposition in certain breeds, autoimmune destruction of the adrenal glands, and improved diagnostic capabilities. It is often caused by the immune system mistakenly attacking adrenal tissues, with a strong link to environmental factors, including potential triggers from spaying/neutering.

Why are so many dogs getting Addisons' disease?

The most common cause of Addison's disease is hereditary, and it causes the dog's immune system to destroy their adrenal glands.

What dog breeds are prone to Addison's disease?

While any dog can get Addison's disease, certain breeds have a higher genetic predisposition, including Bearded Collies, Standard Poodles, Great Danes, Nova Scotia Duck Tolling Retrievers, Portuguese Water Dogs, and West Highland White Terriers, with Rottweilers, Soft Coated Wheaten Terriers, and Leonbergers also being overrepresented. It's an endocrine disorder where adrenal glands don't produce enough hormones, often striking young to middle-aged female dogs.
 

How to prevent Addison's crisis in dogs?

Preventing Future Addison's Disease Crisis

Preventing an Addisonian crisis requires consistent medication administration and regular veterinary monitoring. Never miss doses of prescribed medications, as these replace the hormones your dog's body cannot produce naturally. Keep extra medication on hand for emergencies.

What percentage of dogs get Addison's disease?

Perhaps it's easiest to identify with pets when they suffer the same health problems as we do. Addison's disease is more common in dogs than in people, though still relatively rare. About three dogs in a thousand suffer from it.

Addison's disease in the dog. Dr. Dan explains symptoms, diagnosis, and treatment

What not to feed a dog with Addison's disease?

Avoid low-protein diets unless your vet advises it for another medical condition (like kidney disease). Dogs with Addison's often have low sodium and high potassium levels. Their treatment usually addresses this, but it's wise to avoid low-sodium dog foods and consult your vet before adding supplements.

At what age do dogs develop Addison's disease?

Addison's disease occurs most commonly in young to middle-aged female dogs. The average age at diagnosis is about 4 years old. The signs of Addison's disease may be severe and appear suddenly or may occur intermittently and vary in severity.

How expensive is it to treat Addison's disease in dogs?

The monthly cost for Addison's disease treatment can range from $50 to $200 a month, depending on the selected medications and the animal's response to care. The vet costs involved with frequent blood work and urinalysis should also be taken into consideration.

Can stress trigger Addison's disease in dogs?

Medication doses may need adjustment over time based on regular blood test results. If not well managed some patients can be triggered (by a stressful event or other illness) to go back into an Addisonian crisis. Your vet will advise how to manage medications to help avoid this.

What are the early signs of Addison's?

Symptoms of Addison's disease

• fatigue (lack of energy or motivation)
• lethargy (abnormal drowsiness or tiredness)
• muscle weakness.
• low mood (mild depression) or irritability.
• loss of appetite and unintentional weight loss.
• the need to urinate frequently.
• increased thirst.
• craving for salty foods.

Does Addison's disease get worse over time in dogs?

Symptoms of Addison's are often vague to begin with, but over time, tend to become more severe. Left untreated, Addison's disease is often fatal, but fortunately, with treatment, most dogs have a good outlook and can live a relatively normal life.

What does prednisone do for dogs with Addison's disease?

Prednisone can also be a treatment for Addison's disease. Addison's disease occurs when a dog does not produce enough internal steroids. Prednisone works to treat this condition because it provides extra steroids to help maintain balance in your dog's body.

Does Addisons come on suddenly?

Damage to the adrenal glands causes Addison's disease. Symptoms can start slowly. Early symptoms may include extreme tiredness, salt cravings and weight loss.

Is Addison's disease in dogs painful?

Symptoms of Addison's Disease are many — increased thirst and urination, vomiting, diarrhea, weakness, no appetite, shaking or shivering, abdominal pain, weak pulse, slow heart rate.

What are the red flags of Addison's disease?

Red flags for Addison's disease include extreme fatigue, unexplained weight loss, darkening skin (hyperpigmentation), salt cravings, low blood pressure (causing dizziness), abdominal pain, nausea, vomiting, and diarrhea, which can worsen into a life-threatening adrenal crisis with severe pain, confusion, and shock. These symptoms often develop slowly but can appear suddenly during stress or illness, requiring immediate medical attention.

What foods flush out cortisol?

To help lower cortisol, focus on a balanced diet rich in magnesium (leafy greens, nuts, seeds), Omega-3s (fatty fish, chia, walnuts), antioxidants (berries, dark chocolate, green tea), probiotics (yogurt, kimchi), and whole foods like lean proteins, whole grains (oats, quinoa), and healthy fats (avocado, olive oil), while reducing sugar, refined carbs, and excessive caffeine. Staying hydrated is also key.
 

What species is more prone to Addison's disease?

Similarly, standard poodles, Portuguese water dogs, and Nova Scotia duck tolling retrievers are predisposed to Addison's, as are (to a lesser extent) Great Danes, West Highland white terriers, bearded collies, rottweilers, soft-coated wheaten terriers, and Leonbergers, although Addison's may occur in any breed.

Can stress trigger Addison's disease?

Emotional stress has been reported as the triggering factor of acute adrenal insufficiency in up to 1 in 6 patients developing an adrenal crisis. Examples of stressful events include bereavement, a life-altering diagnosis in a family member, and other acute stress at works, school, or home.

What virus causes Addison's disease?

Although autoimmune destruction represents the primary cause of adrenal dysfunction in developed countries (80–90%), infectious etiologies represent the major cause of Addison's disease in the developing world, with Mycobacterium tuberculosis being the most common causative agent.
