My dog ate lemons. What should I do?

A small amount is unlikely to cause serious harm in a healthy dog. Remove any remaining food, offer fresh water and watch for vomiting, diarrhea, a painful belly or lethargy over the next 24-48 hours. Call your vet if your dog ate a large amount, is small, young or has health problems (such as pancreatitis), or if the food contained onion, garlic, chocolate or xylitol.
