Last week, a friend contacted me, concerned about her dog drinking like there was no tomorrow. Of course, a dog will drink more when it’s hot or when they exercise and play hard. But that wasn’t the case.
He was drinking as if trying to drown himself.
I told my friend she was right to be concerned and that she should see her vet find out what’s causing this. Excessive drinking can be caused by anything from infections, diabetes, Cushing’s disease, Addison’s disease, kidney issues, liver issues … This is serious stuff and it is important to find out what is going on and address it.
My friend went to her vet to have the labs done.
The vet told her that her dog has too much calcium in his blood.
She contacted me again, trying to figure out what she should do about it. She contacted ME trying to figure out what she should do about it.
The vet told her the adult dog’s blood calcium was high and sent her on her merry way?
It’s time like this when I would pull my hair out if I had any. Blood calcium is highly regulated and the odds that a dog has too much calcium in the blood from having too much of it in their food are minimal. While reducing dietary calcium might help to get the levels down, what about looking for the real reason?
An accurate diagnosis of the underlying cause of a dog’s hypercalcemia is truly important. ~CriticalCareDVM
There is such a thing as idiopathic hypercalcemia, but that’s only when nobody can figure out the reason, not because there isn’t one.
Unfortunately, the most common cause of high blood calcium is cancer.
There are other major causes, such as hyperparathyroidism, Addison’s disease, kidney disease … One dietary issue which does cause high blood calcium isn’t actually too much calcium in the diet but too much vitamin D.
In general, high blood calcium levels mean break-down in the regulation, not too much calcium in the food.
I sent my friend back to the vet. A different one.
One that won’t consider high blood calcium a diagnosis, merely a presentation of the actual problem that’s behind it.
Not everything that SOUNDS like a diagnosis, is one.
