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.

My Jack Chi mix, Caramel, was just diagnosed with Addison’s Disease. Interestingly, his twin sister does not have it. He did not eat for a full week, we had to bring water to him to get him to drink, and he just lay there, lethargic, shivering, and occasionally vomiting. His regular vet did bloodwork and xrays, which cost $300, and ruled out pancreatitis and intestinal blockage. They suspected Addison’s and sent me to the emergency vet. The emergency vet hospital, which cost a whopping $2300, kept him overnight on an i.v., did more bloodwork and xrays, and finally diagnosed him with an Addisonian crisis. Now, a month later, he is healthy and happy again! He takes a pill every day, and gets a shot once per month, to manage the disease. It was very scary, but I am so thankful to the vets for diagnosing him, and now knowing how to treat this disease! -Kelly in Phoenix
