Addison's Disease Can Affect Dogs
What Is Addison's Disease?
Addison’s Disease happens when the Adrenal Cortex isn’t working in a proper way or isn’t working at all. In science it’s called hypoadrenocorticism. The Adrenal Cortex provides two corticosteroids:
It comes down to this: there is a disturbed balance between sodium and potassium. A shortage of sodium causes water loss and lowers the blood pressure. At the same time there's too much potassium which causes the heart beat to slow down in a dramatic way. When not treated in a proper way this disease is fatal.
What Triggers Addison's Disease?
It is still unknown what exactly triggers Addison's disease. The sympthoms can be so various that it can be very difficult to establish the right diagnose.
They do know that the disease happens more in dogs than in humans. The human form was first described by Dr. Thomas Addison back in 1849. The first canine form as late as 1953.
Dr. Karen Becker is a proactive and integrative wellness vetenerian. She describes Addison's disease in a more professional way than I ever could. I'm not a vetenarian, I'm a dog owner who had a dog with this disease. I can only tell you our experience with our dog Sarah.
Short History of Our Dog Sarah
Our dog Sarah was a Wirehaired Pointed Griffon. A hunting dog breed also known as the Korthals Griffon. She came to live with us at the age of 11 months in January 1996.
We already had her litter sister Tsjip from the time she was 7 weeks old. Sarah went to a dog owner who didn’t deserve to have dogs at all. Sarah was mentally and physically abused for about 7 months of her life. She didn’t get enough to eat and they locked her in the garage most of the time. Reason was that their 12-year-old dog didn’t like to have a puppy around.
After 11 months, the owners called the breeder and told them they wanted to get rid of the pup. The breeder asked us if we knew someone who would want this dog. We had her sister Tsjip and she was a marvelous dog. So we decided to take Sarah too. We’ve always had two dogs at the same time. I spare you to describe the exact condition she was in when I got her. It was bad, very bad. Took us weeks to clean her up.
Addison's Started with Different Fall Outs
It took months before Sarah even dared to act like a normal dog again. At the age of 2 years she was a rather happy dog. Then she started to have these small fall outs, like vomiting after dinner. I took her to the vet and she got some meds and seemed ok for a short time, but then she got diarrhoea. We never were able to put the finger on a direct cause, so it was guess work for the vet too.
A few months long it was obvious that Sarah wasn't feeling too well. All kinds of trivial things seemed to bother her. One after the other.We thought it might be a reaction on the abuse, so we overloaded her with care and love.

Then Sarah Took a Turn for the Worse
Then, one Sunday night when I came home, Sarah jumped off the sofa to greet me. That moment she collapsed through her behind legs. She seems paralized. We called the vet and it seemed that Sarah had a heartbeat of 60. It should be 80 or 90. The vet still didn't know what was wrong, but he gave her some meds for the night. The next day he made an appointment for us at the Department of Small Pets at the University in Gant, Belgium. That's only 40 minutes by car from our home.
They couldn’t tell us if she would make it to the next day, but she did. She stayed in the University hospital for about a week and then we took her home again. They told us Sarah had to be on heavy medication for the rest of her life.
Our vet was not to blame. They never had a dog with Addison's disease in their clinic before. They didn't make the connection between Addison and all the 'harmless' fall outs.
They can treat Addison's disease rather well with fludrocortisone and prednisolone. They need to find the right balance. Both meds can have heavy side effects and therefor vets don't like to give them. Yet in the case of Addison's disease it's a must and there will not be side effects. The meds will not be an addition on top of the normal production of these hormones. They regulate the balance between sodium and potassium and make it right again.
It takes time to experience with the meds to get the balance right again. During that time whe had to rush over to the University when things were not going as they should. Sometimes in the middle of the night. When they finally found the right balance things turned for the better. Sarah became a happy dog again. Yet we always had to be on the alert for signs that would set her back. In Sarah's case it was the vomitting after dinner. When that happened we knew she needed an extra shot at the vet.
Luckily we found a Pharmacist in Belgium, not too far from our home, who was willing to make the meds for us.
Having a Dog With Addison's Disease Changes Your Daily Routine
One Skip of Giving Meds Could Be Fatal
The administration of the meds is very strict and so vital. One missed medication in the morning or evening can mean death for the dog. Addison changes your daily routine. Medication time was a set time twice a day. We always had to make sure there was enough supply of meds in the house. We had a 'survival package', holding a heavy shot in case of an emergency.
When we took the dogs with us for a day or a weekend, we took enough meds along in case we were not be able to get home in time. We also made sure to take along a vet’s declaration of what the dog was suffering from in case we had to visit another vet. That happened a few times.
Once in a while the balance got unbalanced again. Then we had to get to a vet as soon as possible where ever we were. Waiting to see your own vet might cause the dog to die if the heartbeat should drop too low.
Addison's Disease Is Treacherous
Despite all the good care, things can get wrong anyway. With Sarah the alert signal was always not eating or throwing up. When that happened, we knew something was wrong. Then we rushed over to the vet, who then checked her sodium and potassium balance. If it was out of balance he would give her an extra shot. That happened several times.
This all may sound very stressful and time consuming to you, but actually it wasn’t that bad. You get used to the routine and I must say, with the proper dose of meds, Sarah was living a normal dog’s life.
We knew that she wouldn’t reach a real old age. She would either die from her disease or from the heavy medication.
After 6 Years Sarah Lost Her Battle Against Addison's Disease
The specialist told us that it was rather important to avoid stressfull situations. Too much stress can trigger the unbalancing. That was not an easy task. Our dogs had the habit of sneaking out when they saw a chance. Tsjip could open doors from the inside and outside. Being hunting dogs, they would roam the agricultural farmlands around us.
When that happened they would stay away for hours. Could be up to 12 to 16 hours. When that happened in the evening or night it was useless to go look for them. We had to wait until they decided to come home again. They always came home together and they never harmed any farm animals around us. The bad thing was that Sarah then skipped one medication. That we could solve. We could not solve that those trips were tiresome and stressful. At the age of 8 years old one of those trips became fatal for Sarah.
They were gone for 16 hours so she missed two times her meds. When they came home I immediately took her to the vet. He gave her an extra shot, but it was too late. She didn't recover like she normally would. She died the following day.
It was very sad. Yet I was glad that we had been able go give her a happy full life in her 6 years of Addison's disease.
Addison’s Disease can be inhereditary, but doesn’t have to be
Quite often it happens that the illness occurs to more members in your dog’s family. Of course, if her family is unknown, there’s no way to tell if it’s an inhereditary form or not. In Sarah’s case it was inhereditary. It appeared that her mother and two siblings came down with Addison too.
Addison's Disease is one of the most underdiagnosed illnesses. Due to the diversity in ailments. When a vet has never seen the symptoms in real they might not make the connection to Addison. So if your dog suffers frequent from one of the following symptoms, make sure to mention Addison to your vet.
* Refusing to eat
* Lack of appetite
* Tremors or shaking
* Muscle weakness
* Pain in hind quarters
Keep an eye on your dog after stressful events. Any repeated aberrant behaviour could be an sign that something is wrong.

Questions & Answers
I have a Jack Russel Terrier with Addisons. Did you ever find Sarah was always extremely hungry? We aren’t sure if the medication is causing it. We need to be very careful and calculated with his food, even hand preparing and weighing his meals that he gets two servings a day with medication but he is always hungry!
My dog Sarah wasn't extremely hungry while she suffered from Addisons disease. My dogs just ate what was given to them. In the morning a slice of bread with either a bit of peanut butter or liver paste on it and in the evening their main dinner. We treated her the same as before other than that she got here meds twice a day. They hardly ever got something in between meals.
I think you have to be firm with your dog because so often dogs are given too much food which makes them grow too fat. If he's begging just send him to his place or completely ignore him. But...as I'm no doctor and your dog seems extremely hungry my advice would be to consult your vet.Helpful 3
