Zinc—Can It Be Toxic?
Zinc is an essential mineral that we need to stay healthy. It’s found throughout our bodies in low amounts in most tissues. Zinc is crucial to many bodily functions; we and our canine companions need the right amount of zinc to maintain health. While we and our fur babies need zinc to stay healthy, too much zinc can be toxic. This condition is known as zinc toxicity. Zinc poisoning is a common cause of poisoning for dogs.
Zinc Toxicity in Dogs
The zinc pills you take more than likely contain more zinc than your fur baby needs, though toxicity levels of zinc are not completely determined for dogs. It can depend on their size and how much zinc they’ve ingested.
When zinc pills enter the stomach, they begin to break down, which can lead to an upset stomach. The zinc is also absorbed into the bloodstream.
Zinc poisoning in dogs can cause:
- Destruction of red blood cells
- Liver damage
- Kidney failure
- Heart failure

Diagnosis and Treatment of Dog Zinc Poisoning
The vet will perform a physical exam and will also ask you when your dog showed symptoms. Be sure to tell the vet how many milligrams of zinc were in the pill, if possible.
Next the vet may run tests including a radiograph of your canine companion’s intestinal tract. They will also verify the zinc poisoning through blood tests.
Your fur baby may need to be hospitalized. The vet may choose to begin IV therapy to help stimulate urination. Medications may be given to help stop the formation of zinc salts and treat nausea. Your fur baby may also require a blood infusion.
Prognosis for Zinc Poisoning in Dogs
Early treatment is crucial to your dog’s life. If caught early enough, the more serious symptoms may be avoided. Your vet may want to monitor your pup’s health once he recovers. Dogs sometimes develop other complications as a result of zinc poisoning.
