Why Coins / Pennies is dangerous

Some coins, notably post-1982 U.S. pennies, are high in zinc. Once swallowed, stomach acid breaks the zinc down and it is absorbed into the bloodstream, where it destroys red blood cells and can damage the liver, kidneys, and heart. Pet Poison Helpline notes that swallowing a zinc-containing coin can be fatal without treatment.

Signs to watch for

Weakness, pale or yellowish gums, vomiting, rapid breathing, rapid heart rate, dark discolored urine, collapse

Check the exact item or ingredient before assuming two similar exposures carry the same risk.

What to do next

Get an x-ray as soon as possible: the coin needs to be located and usually removed before it does more damage. Don't wait to see if it passes on its own.

Another helpful reference is CLR Calcium Lime and Rust Remover. No. This needs an x-ray and likely removal by endoscopy or surgery. It isn't a watch-and-wait situation. Immediately, any time you know or suspect your dog swallowed a coin.
