Can Dogs Swallow Pennies? No — Zinc Causes Fatal Toxicity

This food is NOT safe for dogs. Keep it away from your pet.

Pennies minted after 1982 are extremely toxic to dogs. Modern US pennies contain 97.5% zinc which causes zinc toxicity — a serious and often fatal condition causing hemolytic anemia and organ failure. This is a veterinary emergency.

Warning Signs & Symptoms

Zinc toxicity: hemolytic anemia — destruction of red blood cells. Organ failure: kidney and liver damage from zinc accumulation. Symptoms: vomiting, diarrhea, pale gums, weakness, orange-tinged urine, jaundice. Potentially fatal without immediate treatment.

If Your Dog Ate This

If your dog swallowed, or may have swallowed, a penny or any other coin, call your vet or an emergency vet clinic right away and arrange for your dog to be seen, even if your dog seems fine. US pennies made since 1982 have a zinc core, and stomach acid can release zinc that destroys red blood cells and damages the kidneys and liver; any coin can also cause a blockage. Do not wait for symptoms such as vomiting, weakness, pale gums or dark or orange urine. Your vet will decide what tests and treatment are needed, which may include an X-ray and removing the coin. Tell the vet how many coins may be missing and your dog's weight. Do not try to make your dog vomit unless a veterinarian or poison-control expert tells you to.

What You Need to Know

US pennies minted after 1982 contain a zinc core plated with copper. When swallowed, stomach acid dissolves the copper coating releasing zinc which is rapidly absorbed and toxic. A single penny contains enough zinc to cause serious toxicity in a small dog. Older pennies (pre-1982) contain primarily copper and are less dangerous. This is a veterinary emergency; your vet will decide what tests and treatment are needed, which may include an X-ray and removing the coin.
