Is Zinc (coins / galvanized metal) toxic to dogs?
Also known as: coins / galvanized parts / zinc washers
🚑 What to do right after ingestion
Known coin/hardware ingestion — X-rays now, then endoscopic or surgical removal plus support; hemolysis progresses over days.
Toxicity notes
Dogs love chewing coins (post-1982 US pennies are zinc-heavy) and small hardware — stomach acid dissolves zinc causing hemolytic anemia; coins show on X-ray.
Poisoning symptoms
- • Vomiting
- • Lethargy
- • Pale gums
- • Dark red urine
- • Jaundice
Symptoms can be delayed (e.g. onion/garlic-induced hemolysis may take days) — a pet looking fine right now is no reason to relax.

Can I make my pet vomit at home?
Home-induced vomiting is not advised: corrosive cleaners, sharp bones or existing neurological signs make it dangerous, and improper technique risks aspiration pneumonia. Vomiting should be induced by a vet with proper drugs at the right moment — most effective within 1-2 hours. So “head to the clinic as soon as you know” beats “try to induce vomiting first”.
