Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Like lemons, limes contain citric acid, limonene, and psoralen compounds that are harmful to dogs. The peel and seeds contain the highest concentrations. Ingestion can cause vomiting, diarrhea, lethargy, and in large quantities, central nervous system depression. Lime essential oils and lime-scented products are also hazardous. While a tiny lick of lime juice is unlikely to cause serious harm, limes should not be given to dogs.
What You Should Know
Limes should be kept well away from dogs. If your dog has eaten limes, watch for symptoms such as vomiting, diarrhea, lethargy, or loss of appetite. In an emergency, contact your veterinarian or an animal poison helpline straight away.
