Post-'82 pennies contain harmful zinc
While we always worry when one of our companions ingests a nonfood item that has the potential to become lodged in the gastrointestinal, or GI, tract, pennies can become life-threatening for reasons other than their potential for blockage. In 1983, the folks in Washington, D.C., slyly began coating zinc disks with copper and calling them pennies. Unless you and your dog enjoy coin collecting as a shared hobby, this probably is of little consequence to you, until your dog ingests one of these post-1982 coins.
Zinc is highly toxic to dogs and cats because it causes a condition known as hemolytic anemia. Hemolysis, or breakdown, of red blood cells, occurs when there are high levels of zinc in the bloodstream. Zinc somehow renders the red blood cell membranes nonviable. While the mechanism behind this is not completely understood, the result is that red blood cells are removed from circulation in huge numbers, causing severe anemia.
