Explanation
Lemons contain psoralens and essential oils like limonene and linalool, which are toxic to dogs. While a tiny taste might only cause stomach upset, consuming significant amounts can lead to more serious neurological issues. Furthermore, the high acidity is irritating to the canine digestive tract.
Recommended amount
Do not feed lemons to dogs in any quantity. Small amounts may cause digestive upset; larger amounts increase the risk of toxicity.
Risks
Gastrointestinal distress, vomiting, diarrhea, depression, photosensitivity, and potential liver failure in extreme cases.
Symptoms to watch for
Vomiting, diarrhea, excessive drooling, lethargy, and sensitivity to light.
Safer alternatives
For a vitamin C boost, pet-safe fruits like blueberries or seedless watermelon are much better options for dogs.
