It all started Sunday evening when she had to take an evening poo, which is not part of her regular routine. Even more uncharacteristic was that it was pretty ploppy. Her appetite was good however, and she was drinking as usual.
When Monday rolled around, she was still eating and drinking, but the diarrhea was worsening. Tuesday morning, I woke up to a gazillion little piles of stinky poo all over the floor. By Tuesday afternoon, she was lethargic and refusing to drink, eat, or even get up.
My husband called me at the barn letting me know I had better come home. As soon as I saw her, I told my husband she needed to be seen. Her temperature was slightly elevated, her hind end was shaking, and she refused to stand or walk. Of course, it was about 5:45 pm when I got home which meant it was too late to get her into our regular vet.
Our initial suspicion was poisoning from gnawing on palm fronds (not segos). After a quick exam, the doctor ordered a round of blood tests that included a complete blood panel, a CBC with differential, an electrolyte profile, a check of her pancreatic function, a cortisol test, and a urinalysis. The doctor suspected Addison's Disease (failure of the adrenal gland to produce hormones).
We spent several tense hours in the waiting room while I googled Addison's Disease. I wanted to be prepared. Fortunately, Brienne's blood work came back completely normal, especially her electrolytes. The doctor shrugged her shoulders and agreed with our initial (hopeful) diagnosis of palm frond overload with hind end muscles sore from so much pooing.
Dogs and horses - they're both so fragile!
