Lemons — Avoid — can cause harm
Lemons are dangerous for dogs due to compounds found in the fruit, peel, and seeds. Ingestion can lead to gastrointestinal upset, photosensitivity, and neurological issues. Seek veterinary attention if your dog consumes lemons and shows severe symptoms.
TOXIC COMPOUND
Psoralens (furocoumarins), essential oils (limonene, linalool)
Psoralens are phototoxic compounds that can cause dermatitis and photosensitivity. Essential oils can irritate the gastrointestinal tract and, in large quantities, may cause central nervous system depression.
DOSE THRESHOLD
Small amounts of pulp may cause mild upset, but larger ingestions, especially of the peel, seeds, or leaves, are more toxic. The concentration of toxic compounds is highest in the peel and seeds.
