Did you know?
Vitamin D is unusual among vitamins because it functions more like a hormone than a vitamin — it is synthesized in the skin from cholesterol when exposed to UV light and then converted to its active form by the liver and kidneys. Dogs can synthesize vitamin D through skin exposure to sunlight but less efficiently than humans. The rat poisons brodifacoum and cholecalciferol are widely used for rodent control — the latter is vitamin D in toxic concentrations and is one of the most common causes of vitamin D toxicity in dogs.

What You Need to Know
Vitamin D is a fat-soluble vitamin that accumulates in the body with no excretion — making toxicity a serious risk. Vitamin D toxicity in dogs has caused deaths from rat poisons containing cholecalciferol and from excessive supplementation. The gap between a beneficial dose and a toxic dose is narrow. Never give human vitamin D supplements to dogs. Dog-specific supplements under veterinary guidance only.
