If you’re here then you’ve probably Google’d about: vitamin d toxicity in dogs.
Featured
However, extremely high levels of vitamin D can cause serious health problems. Vitamin D is a fat-soluble vitamin, so unlike water-soluble vitamins, when a dog – or other animal – gets too much, the excess is not rapidly excreted in his or her urine.
Presentation
She was not lethargic or depressed at that time.
The Question
Did Maple Consume Enough Of The Supplements To Cause Clinical Signs?
Maple weighed 28kg on entry. However, with the impossibility of knowing exactly what Maple consumed, the safest choice was to hospitalize her with presumed Vitamin D toxicosis. Treatment Plan
Hospitalize for 72 hours with IV saline to diurese the kidneys.
Recheck iStat free calcium and phosphorus every 12 hours. Recheck CBC/chem every 24 hours to monitor renal values. Outcome
Maple was hospitalized on IV fluids for 72 hours.
Her total calcium and phosphorus levels remained within normal range for the duration of her treatment, and her renal values (BUN and creatinine) were within normal limits on exit. Overview
Vitamin D toxicosis is a potentially life-threatening condition that causes increased reabsorption of calcium leading to renal damage. References:

What Is Vitamin D Poisoning?
Ested the substance at the time you seek treatment, the veterinarian will induce vomiting and administer a drug that binds to the vitamin D in order to prevent further absorption. Hydration helps to encourage the excretion of excess calcium through urine. In some cases, aluminum hydroxide, or other phosphate binders will be given to lower the phosphate levels.
