We’ve had another dog-related drama this week, and as it is something I’ve not personally had to deal with before, despite ten years of looking after other people’s pooches, I am assuming there are some of you who also may not know about it. Therefore it is an important story to share.

We were looking after a couple of poodles, Joey, a miniature and Priya, a standard, who are regular guests of ours. A week after they had returned home the owner contacted us to ask if anything had happened while the dogs were with us, as Priya was a bit below par. There was nothing we could put our fingers on. She had eaten well, played happily and was enthusiastic to go on dog walks.

Her owner explained that she had become a bit lethargic and had lost her appetite. He had been to the vet with her, but they just said to keep an eye on her. The dogs were due to come back to us because the family were going on a long-awaited holiday abroad. We agreed that they should still come, even though by the time they dropped the dogs off, Priya still wasn’t herself.

Over the weekend, my son Jasper and I became increasingly concerned. Priya refused all food despite tempting her with treats like cheese and roast chicken that dogs usually gobble up. She spent most of the time sleeping, and whenever she did get up, her normally waggy tail was limp and lifeless.

Thankfully, one of my other customers is a vet and is our go-to if we are worried about any of our charges (if you run a professional dog care business, it is a requirement of your license to be registered with a vet, even if you don’t own a dog yourself). When I messaged her with the symptoms, she quickly replied that we should take her to the emergency surgery right away.

The owner’s own vet was based a good hour away, so we needed his permission for them to share Priya’s health details with the practice we wanted to use which was much closer. It meant we had to interrupt his holiday to let him know what was happening and to ensure we got the necessary consent.

Permission gained, Jasper whisked Priya to our vet who took blood from her to conduct tests in the hope of getting to the root of the problem. She was also hooked up to a drip and had to spend the night in the animal hospital.

The vet who did the initial examination had a suspicion of what it might be. “Addison’s disease, or something like that,” Jasper explained to me when he got back. I thought he must have the name wrong, because that was a human disease, wasn’t it?

When I looked it up, it was indeed a rare autoimmune disease of the adrenal glands that afflicts around 9,000 people a year. However, it is also found in dogs, and when I read the symptoms, it was spot on – lethargy, lack of appetite, and ‘just not themselves’. Other symptoms include vomiting and diarrhoea, increased thirst and limb weakness. Symptoms can come and go, too, but they get progressively worse, so it is important to not delay in getting a dog checked out. Although pretty rare in humans Addison’s Disease is quite common in dogs.

The results of the blood tests came the next day and confirmed Priya had the disease. It is caused by the adrenal glands ceasing production of two essential steroid hormones, cortisol and aldosterone, both of which are essential for life. It can affect any dog but is most common in certain pedigree breeds between the ages of four and six, such as the Standard Poodle, West Highland White Terrier, Great Dane and St Bernard’s. Left untreated the condition is fatal.

From now on, Priya needs to take a steroid pill every day for the rest of her life to replace the cortisol and also needs an injection once a month to replace the aldosterone. She quickly recovered and is back to her old self.

If you have pet insurance that you started before any symptoms appear, then you should be covered. If not, then I’m afraid a diagnosis of Addison’s Disease will be a rather costly affair!
