Addisons Disease in a Chihuahua: Kermit's Story

Addison’s disease in a Chihuahua

Kermit was a spirited sweetie with a unique personality, adopted as a stray. He was an oddball, who brought his own kind of entertainment and challenges.

Kermit loved his family and enjoyed going on hikes in nearby trails. After one of the hikes, about ten minutes after they got home, Kermit collapsed.

Why did Kermit collapse?

Something was wrong.

He came-to fairly quickly; was the hike too much for him? A trip to a vet and blood work later, the diagnosis was in.

Kermit has Addison’s disease

What the heck is Addison’s disease?

Addison’s Disease means that adrenal glands are not functioning properly. It is hard to diagnose because symptoms can point to other things. In Kermit’s case, to put it in layman’s terms, his body was not producing the hormones necessary to deal with physical or emotional stress. So when he went on that hike, his body wasn’t able to deal with the exertion. Symptoms can be sudden or gradual and can stop and start, another factor that makes diagnosis difficult.

Common symptoms include lethargy, depression, vomiting & diarrhea, decreased appetite, shaking, and muscle weakness. 

Addisonian crisis

Kermit’s collapse was an acute episode, called Addisonian crisis.

This happens when blood pressure drops dangerously low.

Kermit’s treatment

There is no cure for Addison’s, but it can be managed with medication.

Kermit was put on a daily dose of fludrocortisone, a medication that had to be taken daily for the rest of his life and adjusted based on regular blood test results.

Together with a healthy diet, supplements, and regular moderate exercise, the meds seemed to keep Kermit’s Addison’s under control.

Before any stressful situation, Kermit got an extra half dose leading up to the event and during the event.

What constitutes stress?

It is important to realize that even positive excitement constitutes stress.

Out-of-town guests were a welcome excitement for Kermit but the thrill of it could send him into an Addisonian crisis.

For a couple of years, Kermit was living a happy life and all seemed good.

Kermit’s seizures

Then, one day, Kermit suddenly collapsed. This time it was different, though. His body stiffened and he started convulsing. The few seconds it lasted seemed like forever. After the episode, he stood up, walked around a bit, pooped, drank a ton of water and went about his normal business.

Even though he bounced right back, Kermit was rushed to a vet.

Seizures are not typically one of the symptoms of Addison’s disease. Blood work didn’t reveal any answers. On top of his Addison’s disease, Kermit was diagnosed with a non-specific seizure disorder.

One theory was that the seizures could be the toll his Addison’s was taking on his body but it was just a speculation. There was no telling whether it was going to repeat or how often it might happen. For the time being, Kermit was kept on his meds only.

Over the next couple of years, Kermit had a seizure every now and then.

Because they were sporadic and treatment would be rather invasive, things were left alone. But as time went on, the seizures became more consistent and out of the blue, he would get cluster seizures too.

Seizures increase

What was setting them off?

However, his housemate knew when they were coming. She would stick to him like glue, licking his eyes. And then he would get a cluster seizure. Not that there was much that could be done with that knowledge, but at least one could tell what was coming.

The main thing was to keep him from injuring himself, comfort and support him.

Apart from the seizure episodes, Kermit was his normal happy self.

Further decline

Eventually, though, the seizures took a tool on his brain and Kermit started showing signs of not being all there. He started soiling in the house, unaware he was doing anything wrong.

Then he began chewing on his front leg. 

At first just a little nibble … then he just chewed and chewed and chewed. He couldn’t snap out of it.

Kermit was set free.

I am a graphic designer, dog health advocate, writer, and author. Jasmine, the Rottweiler of my life, was the largest female from her litter. We thought we were getting a healthy dog. Getting a puppy from a backyard breeder was our first mistake. Countless veterinary visits without a diagnosis or useful treatment later, I realized that I had to take Jasmine's health care in my own hands. I learned the hard way that merely seeing a vet is not always enough. There is more to finding a good vet than finding the closest clinic down the street. And, sadly, there is more to advocating for your dog's health than visiting a veterinarian. It should be enough, but it often is not. With Jasmine, it took five years to get a diagnosis. Unfortunately, other problems had snowballed for that in the meantime. Jasmine's health challenges became a crash course in understanding dog health issues and how to go about getting a proper diagnosis and treatment. I had to learn, and I had to learn fast. Helping others through my challenges and experience has become my mission and Jasmine's legacy. I now try to help people how to recognize and understand signs of illness in their dogs, how to work with their veterinarian, and when to seek a second opinion. My goal is to save others the steep curve of having to learn things the hard way as I did. That is the mission behind my blog and behind my writing. That is why I wrote Symptoms to Watch for in Your Dog, which has turned out being an award-winning guide to dog owners. What I'm trying to share encompasses 20 years of experience.
