Our Dog Sarah Suffered From Addison’s Disease

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, however, ended up with 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 food to eat and she was locked up in the garage most of the time because the 12-year-old dog the owners had didn’t like to have a puppy around.

After 11 months, the owners called the breeder and told them that they wanted to get rid of the pup. The breeder called us to ask if we might know someone who would want this dog. Knowing that her sister Tsjip was a marvelous dog, we decided to take on Sarah too. We’ve always had two dogs at the same time so they could enjoy each other’s company.

However, after two years, Sarah began to show all kinds of ailments and it took a very long time before the vets could nail it down to Addison's Disease.

What Is Addison's Disease?

Humans as Well as Dogs and Cats Can Get Addison's Disease

Addison’s Disease happens when the Adrenal Cortex isn’t working properly or isn’t working at all. Scientifically it’s called hypoadrenocorticism. The Adrenal Cortex provides two corticosteroids:

1. glucocorticoids,

2. mineralocorticoids.

In other words it comes down to this: the balance between sodium and potassium is severely disturbed. There’s a shortage of sodium which causes water loss and lowering blood pressure and there’s too much potassium which causes the heart beat to slow down dramatically. When not treated properly this disease is fatal.

It's yet unknown what exactly triggers Addisons Disease and because the symptoms can be so various, it's very difficult in some cases to establish the right diagnose. They do know however that the disease happens more frequently in dogs than in humans. The human form was first described by Dr. Thomas Addison back in 1849, the first canine form was described as late as 1953.

I found this video where Dr. Karen Becker, a proactive and integrative wellness veterinarian discusses Addison's Disease in a far more professional way than I ever could, because I'm not a vetenarian, I'm just an owner who had a dog with this disease and I can and will tell you what we experienced with our dog Sarah.

Explanation of What Exactly Addison's Disease Is

How Addison's Disease Started With Our Dog Sarah

It all started with different fall outs

I already mentioned above, that our dog Sarah had been physically and mentally abused by the people who bought her from the breeder. It took a long time before she even dared to act like a normal dog again.

When Sarah was in her second year and actually doing really fine, considering the bad treatment she got from her former owner in the past 7 months, she started to have these small, but seemingly harmless fall outs, like vomiting after she had eaten. 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. Our vets had never seen a dog with the symptomes of Addison’s Disease and therefor they didn’t make the connection between Addison and all those ‘harmless’ fall outs.

During a few months it was obvious that Sarah wasn’t feeling all too well, but there were all kind of different things she seemed to be suffering from. We all thought that the fact that she had been abused for so many months had been causing all this. In between her little inconveniences, Sarah was a happy dog who had learned to play with her sister and who could stand a whole evening next to you, resting her head on your knee, enjoying the attention she got.

Did you know that dogs could get Addison's Disease?

Then Sarah took a turn for the worse

Then, one Sunday night, when I returned home from being away two days, she jumped from her sofa to greet me and she collapsed through her behind legs, like she was paralized. We immediately called the vet and he discovered that Sarah had a heart beat of 60, while she should have had about 80 or 90. The Vet still didn’t know what was wrong with Sarah, but he gave her some medication of which he thought would help her through the night and the next morning we had to take her to the closest animal hospital, which happens to be the Department of Small Pets at the University in Gant, Belgium, which is only 45 minutes by car from where we live.

At arrival, hearing our story, the specialist immediately recognized Addison’s Disease and Sarah was put in a glass cage on a drip. 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 were allowed to take her home again. They told us she had to be on heavy medication for the rest of her life.


Sarah's Medications

Addison’s Disease can be treated rather well with fludrocortisone and prednisolone when the right balance has been found. Both meds are known for their heavy side effects and therefor vets don’t like to give them, but in this case it’s necessary and you won’t see the side effects because the meds are not an addition on top of the normal production of these hormones. They make the normal balance between sodium and potassium right again.

It takes some time to get the balance right and during that time we had to rush over to the hospital on a regular base, sometimes even in the middle of the night, when things weren’t going as they should. It took a few weeks and then we had found the right balance, though we always had to be on the alert for signs that would set her back. Luckily we had 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

As the administration of the meds is so strict and so vital (one morning or evening missing out could cause death for the dog), it really changed our daily routine. First we had to make sure we always had enough supply in the house. We also had a ‘survival package’, holding a heavy shot in case it was needed. Whenever we took the dogs out for the day or a weekend, we had to make sure to take enough meds with us, just in case something happened that prevented us to be home in time for the next dose. 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 something unknown caused the sodium and potassium balance to unbalance again and then it was a matter of time to get to a vet as soon as possible where ever you were, because waiting to see your own vet might have caused the dog to die if the heart beat should drop too much.

Despite all good care, it sometimes wasn't enough

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 and then we rushed over to the vet, who then checked her sodium and potassium balance and if needed 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 eventually and I must say, with the proper dose of meds, Sarah was living a normal dog’s life. We knew though that she wouldn’t reach a real old age, because she would either pass away from her disease or from the heavy medication.

After 6 years, Sarah lost her battle against Addison's Disease

At the University they told us that it was rather important to avoid stressful situations for dogs suffering from this disease because too much stress can cause the unbalancing again.

Our dogs had the unfortunate habit of sneaking out once in a while when they got the chance (Tsjip could open doors from the inside and outside) and being hunting dogs, they would roam the farmlands around us. They could stay away for many hours sometimes and when it happened at night, it was useless to go look for them in this open country we live in. We just had to wait till they decided to come home again, which they always did.

They never caused any harm on other animals during those long hikes, but the bad thing was that Sarah would skip her medication.

Those trips however stressed them out and at the age of 8 years old, one of those trips got fatal for Sarah. They had been away for about 16 hours causing her to miss her evening and morning medication. When she came home she really was exhausted and slept all day.

She wouldn’t eat at night, so we knew things were wrong. We took her to the vet and she got her extra shot, but alas, it was too late. She didn’t recover like she normally would and she died the following afternoon.

It was very sad, but I was glad that at least we had been able go give her a happy full life for another 6 years.

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.

Because of the diversity in ailments, Addison's Disease is one of the most underdiagnosed illnesses. If a vet doesn’t make the connection between the different fall outs, it’s easily overlooked and then they see no reason to search for it through blood tests. So if your dog suffers from one or more of the following symptomes, make sure to mention Addison to your vet.

* Refusing to eat

* Vomiting

* Diarrhea

* Lethargy

* Lack of appetite

* Tremors or shaking

* Muscle weakness

* Pain in hind quarters

Keep an eye on your dog after stressful events, the dog’s behaviour might indicate that something is wrong.

Have you ever come across a dog who had/has Addison's Disease?

Another Sad Part of the Story

The sad part of this story is that not only we lost a beautiful sweet dog, but a few weeks after Sarah died, her litter sister Tsjip got diagnosed with Canine degenerative myelopathy. Tsjip died 6 months later.

      #Lori A Jenkins: Addison's can influence a dog's behaviour in many ways. It's been too long ago to exactly remember all the signs my dog showed, but I do know that with my dog it was mainly throwing up her food and a low heart beat. Even when she already was on full medication the throwing up was a signal to rush over to the vet.

      It took some time in the beginning to get the medication straightened out.

      My Roman has been diagnosed with Addison's. Did your baby ever become really hyper with a lot of panting?

      #Ellen: I'm sorry to hear of your illness and thank you for your comment to Anselmo. Every country has its own medicine prices. Very interesting to know if dogs are treated with the same medications as humans. I'll ask my vet about that.

      Very nice article about your dog. She was gorgeous, and I'm glad she got away from her sad beginning and had some good years with you.

      To Anselmo: I don't know if they treat dogs with the exact same medications as humans, but I'm a person with Addison's and my steroid tablets only cost about $30 usd a month without insurance, or $10 with insurance. My emergency injection is another $10 without insurance, but I have not yet needed to use it, and so far have just replaced it every two years when it expires. I think it would be a shame for pets not to get treatment if the cost is too high for animals or in other countries. Best wishes to you if you have a sick pet!

      #Anselmo Santos: I don't know what Addison medication costs in other countries. They weren't exceptional costly in my case as I recall.

      As in most cases Addison's disease is autoimmune, caused by autoantibodies, and the remaining are also others diseases such as tuberculosis, AIDS, metastatic cancer and others such as meningitis and hyperplasiat.

      For the very rich owners there will be no problem, but for ordinary people as me, we need to create associations to be able to respond to this problem ....
