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.

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.

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.
