Can my dog eat zinc?
No.
A swallowed zinc object — a nut, bolt, zip pull or US penny — is an emergency. Zinc tablets, syrup or zinc oxide cream usually cause vomiting only.
Already ate it?
If they ate itSwallowed a metal object: go to a vet now — it usually has to be removed. A few zinc tablets or a lick of zinc cream: watch at home. A bottle of syrup or tablets: call your vet today.
Watch forVomiting, diarrhoea, not eating within hours; pale or yellow gums, weakness, and orange or dark urine over several days.
Thinking of giving it?
Why not even a littleZinc tablets, syrup and zinc oxide cream: usually vomiting only. The lethal dose of zinc salts is about 100 mg per kg. Any swallowed metal object containing zinc has to come out — one US penny holds about 2,440 mg.
WhyStomach acid dissolves zinc from swallowed metal, and the absorbed zinc destroys red blood cells, often days later. Zinc supplements and creams are poorly absorbed and low risk unless a lot is eaten.
