Puppy safety
Generally avoid feeding olives to puppies. Their digestive systems are still developing and they're more sensitive to changes in diet, fat, sodium, and lactose than adults. If you've already given some, watch for vomiting, diarrhea, or lethargy and contact your vet if any appear.

- Watch for symptoms over the next 12–24 hours: vomiting, diarrhea, lethargy, loss of appetite, or changes in drinking/urination.
- Provide fresh water and skip the next meal if your pet seems unsettled — let their stomach calm down.
- Call your vet if symptoms appear or persist beyond 24 hours, or if the amount eaten was significant.
