How to fix high calcium levels in dogs?

Elevated calcium levels in dogs, often called hypercalcemia, can sneak up on even the most attentive pet owners. You might notice your pup drinking more water than usual, struggling to urinate, or acting lethargic—subtle signs that something’s off with their internal balance. Left unaddressed, this condition can strain kidneys, weaken bones, and even affect heart function, so catching it early matters.

First, pinpointing the cause is key. Sometimes it’s linked to diet: too many calcium-rich supplements, like those added to homemade meals without vet guidance, can tip the scales. Other times, underlying issues are at play—kidney disease, certain cancers, or even infections can disrupt calcium regulation. A trip to the vet for blood work is non-negotiable here; they’ll run tests to rule out serious conditions and guide your next steps.

Adjusting their diet is often the first line of defense. Swap out high-calcium foods like excessive dairy or bone meal for balanced commercial diets formulated to meet AAFCO standards—these are designed to keep mineral levels in check. If you’re feeding homemade meals, work with a veterinary nutritionist to ensure you’re not overdoing it on calcium or vitamin D, which can also drive levels up.

In more severe cases, your vet might recommend medications to lower calcium absorption or increase its excretion. They might also treat the root cause, whether that’s antibiotics for an infection or more specialized care for chronic illnesses. Never self-prescribe, though—some over-the-counter drugs can interact poorly with your dog’s system, and dosages need precise calculation.

Monitoring is crucial during recovery. Regular blood tests will track calcium levels, and your vet might adjust treatments based on those results. Keep an eye on your dog’s behavior, too—improved energy or normalized drinking habits are good signs they’re on the mend.

Remember, prevention goes a long way. Avoid giving calcium supplements unless your vet specifically recommends them, and always follow feeding guidelines on commercial foods. In many places, local animal welfare laws require pets to receive proper veterinary care, so staying on top of check-ups isn’t just good practice—it’s often a legal responsibility.

High calcium levels in dogs can be managed with the right care, but prompt action is key. By working closely with your vet, adjusting their diet, and staying vigilant, you’ll help your furry friend stay healthy and happy for years to come.
