My dog ate Lemon - what should I do?

Citrus limonia

Potentially toxic

Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.

Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.

Safety verdict

Consulted references classify the plant as toxic or irritating for that pet type.

Signs to watch for

Vomiting, diarrhea, lethargy, and signs of skin irritation or sensitivity.

Escalation note

The essential oils and compounds in the plant can lead to digestive distress and skin issues. Always consult a veterinarian if you suspect your dog has consumed or been exposed to the plant.

First aid at home

Take the lemon away and bathe any peel oil off the coat with a mild dish soap. Offer fresh water. Do not induce vomiting unless directed by a veterinarian or poison control.

What to watch for

Most common signs are vomiting, diarrhea, depression, and dermatitis where peel oil contacted the skin. Larger or essential-oil exposures can cause weakness, ataxia, and tremors.

Time window

GI signs from peel or leaf ingestion typically begin within a few hours and resolve within 24–48 hours. Essential-oil exposures can take 3–7 days to fully resolve.

When to call the vet

Call a vet or ASPCA Poison Control (888-426-4435) if your dog ingested lemon essential oil, ate a large amount of peel or leaves, or shows ongoing vomiting, weakness, or wobbliness.

What this means for your dog

Dogs: ASPCA lists lemon as toxic, with essential oils and psoralens as the toxic principles. The flesh of the fruit is the least concerning part; the rind, leaves, seeds, and especially bottled lemon essential oil are where most pet exposures cause real problems.
