Zinc can be found in nuts, bolts, hardware, and various metals (including coins) throughout your home. It can also be found in supplement form or in topical medications like diaper rash cream or sunscreen. Unfortunately, zinc can toxic to our pets. In very small doses, GI upset is the most common concern. However, in large amounts, anemia and death become a real possibility. When zinc meets the acidic environment of your pet's stomach, it will absorb directly into the bloodstream and can lead to liver, kidney, and heart failure. If your pet has ingested a metal object or coin (especially a penny) that could contain zinc, or has ingested a large quantity of a zinc supplement or topical medication, seek emergency care. If your pet ate a small amount, licked your hand after applying sunscreen or diaper rash cream, the symptoms are likely to be mild to moderate GI upset, which should resolve within a day or two but should be evaluated if it doesn't resolve quickly.
