My 3-month-old, 2 kg puppy chewed on a lime wedge from my drink — is his small size a bigger problem?

Short answer

Yes, his small size does increase the risk. Limes are acidic and the peel contains oils that can cause drooling, vomiting, and diarrhea. A tiny puppy's system is more sensitive, so even a small amount can have a stronger effect. Watch him closely for the next several hours for excessive drooling, retching, or any signs of stomach discomfort. If he shows any of these symptoms, or if he seems unusually tired, contact your veterinarian for guidance.

Same as lemon — acidic, and the peel oils cause drooling, vomiting and diarrhoea.

Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.

Lime is not poisonous to dogs, but it is easy to over-feed. Rich fat, salt or seasoning can bring on vomiting or diarrhoea within a day, and repeated large portions are a recognised trigger for pancreatitis.

If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.
