What Is Addison’s Disease in Dogs?

What if one of the biggest medical threats to your dog is nearly invisible? Addison’s disease in dogs hides as usual symptoms, such as lethargy, gastrointestinal upset, or loss of appetite.

To the naked eye, it appears to be nothing more than just a “bad day”. But internally, a dog’s adrenal function could be collapsing, silently nudging them toward an abrupt and potentially life-ending emergency. Although the disease is deemed uncommon, early detection can spell the difference between crisis and control.

In this article, we will study Addison’s disease in dogs in detail, including symptoms and treatment options. Are you ready? Let’s get started.

The Two Types Of Addison’s Disease

Addison’s disease is a hormonal disorder. The adrenal glands, which are near the kidneys, usually secrete cortisol and aldosterone. These hormones control the response to stress, blood pressure, and fluid balance. When production is inadequate, the body starts to deteriorate.

There are two primary forms. We shall discuss them both.

  • Primary Addison's disease results from damage to the adrenal glands themselves.
  • Secondary Addison's disease results from the pituitary gland not sending the correct signals to the adrenals. 

Although the causes are different, both result in the body having critically low hormone levels.

Knowing about the two types of Addison’s disease is significant because it influences diagnosis and treatment. They both may seem indistinguishable on the surface, but they have different causes. With this background in place, it becomes easier to see just how frequently this illness occurs and why awareness is crucial.

Occurrence Of Addison’s Disease In Dogs

So, how rare is Addison’s disease in dogs? According to studies, it affects less than 1% of dogs. That sounds unusual, but the risks seem greater for owners of susceptible breeds. Poodles, West Highland Terriers, Portuguese Water Dogs, and Bearded Collies have a greater likelihood. Female dogs, especially young to mid-life, are diagnosed more frequently.

Its scarcity also leads to delayed diagnosis. Many pet parents and even vet technicians don’t regularly come across Addison’s disease, which leads to this condition being overlooked. Awareness campaigns and professional education are all essential because of this.

Though rare, the disease is dangerous and cannot be simply ignored. That's why it's important to learn how to spot early warning signs. Knowing what to watch for can be the difference between regular care and a life-threatening emergency.

Symptoms To Look Out For

Addison's disease symptoms in dogs can onset gradually and differ from one case to another. Some of the common signs include:

  • Weakness and lethargy
  • Appetite loss and weight loss
  • Diarrhea and vomiting
  • Increased urination and thirst
  • Trembling or shaking
  • Abdominal discomfort
  • Sudden collapse in advanced cases (Addisonian crisis)

Since the symptoms overlap with those of other prevalent disorders, they are prone to misinterpretation or being overlooked. With that ambiguity, pet parents are left wondering, and dogs keep on deteriorating. As a means to get to the bottom of things, veterinarians use diagnostic tests beyond visual inspection.

Diagnosis Of Addison’s Disease In Dogs

Diagnosis is the sole means of definitively confirming Addison’s disease. The ACTH stimulation test is the gold standard. This test measures how the adrenal glands respond to synthetic hormones. Blood tests can also show electrolyte imbalances like low sodium and high potassium. 

Imaging is not always required, but it can exclude other possible reasons for symptoms. Further tests are sometimes advised to differentiate between Primary and Secondary Addison’s in certain instances. Proper diagnosis guarantees that the proper treatment strategy is implemented.

Once Addison's disease is diagnosed, the focus changes from finding the issue to stabilizing the patient. Diagnosing is not sufficient; it's the beginning of instant care. From here, the attention turns to treatment measures that protect dogs both in the short and long term.

Treatment And Management

Treatment mostly involves the replacement of hormones. Most dogs need daily medication to replace cortisol and aldosterone levels. In emergencies, intravenous fluids and steroids are administered to stabilize the patient. 

Long-term management involves frequent check-ups, blood work, and adjsuting the dosages. Pet owners have an important role in monitoring stress, diet, and general health. With proper care, most dogs live active and normal lives.

Caring for Addison's involves constant, not emergency, attention. Every-day medication, adjustment to lifestyle, and stress management are all involved. By having this long-term strategy in place, pet owners, of course, are curious about what lies ahead: how well does a dog survive Addison's disease?

Living with Addison’s Disease

Addison’s disease in dogs can be a life-threatening condition. However, if it is managed on time, dogs can live a happy and peaceful life. 

With medication, most are able to have a normal lifespan. The most difficult aspect is being consistent in treatment and identifying any triggers that can make the condition worse. For comparison's sake, the converse of Addison's disease in canines is Cushing's disease, where the body overproduces cortisol rather than underproduces it. 

Although both vary vastly in treatment, they demonstrate how important balance in the hormones is for a healthy life.

For veterinarians and vet technicians, helping these types of patients entails clear communication and reassurance for families. However, for pet owners, it is about establishing habits that maintain medication and monitoring side by side. Together, this team effort ensures that dogs thrive despite their diagnosis.

Hearing that Addison’s is manageable offers hope. However, using that knowledge requires guidance. Pet parents and vet techs can both benefit from expert advice on daily care. That’s why our upcoming webinar is designed to provide practical tools for supporting dogs with Addison’s.

FAQs

What are the symptoms of Addison’s disease in dogs?

The affected dogs typically exhibit mild and subtle warning signs, such as weakness, vomiting, or diarrhea, which may fluctuate. Weight loss, shakiness, and excessive thirst or urination may also surface over time. 

How long can dogs live with Addison’s disease?

Most dogs with Addison's live a normal lifespan with proper treatment. Lifetime medication and close veterinary monitoring maintain balanced hormone levels and guard against potentially lethal flare-ups. Owners are amazed as their pets regain energy, appetite, and quality of life once medication is initiated.

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

Diet is an ancillary aid in controlling Addison's. Fido must not eat foods very high in salt or those that interfere with electrolyte balance, since these will compromise treatment. A stable, vet-prescribed diet ensures stability so that drugs can function properly and dogs can feel their best.

Can Addison's be cured in dogs?

Sadly, Addison's disease is not curable, but it can be effectively managed with proper care. Daily or monthly hormone replacement for the rest of their lives is usually required for dogs. With this dedication, most pets live and enjoy active, happy years, as well as dogs that do not have this condition.
