## Common questions

### Are geraniums toxic to dogs?

Yes — the ASPCA lists geraniums as toxic to dogs.

### What happens if a dog eats geraniums?

The ASPCA publishes this as the clinical signs, word for word: “Vomiting, anorexia, depression, dermatitis” It names the toxic principle as “Geraniol, linalool”. We reprint their wording rather than paraphrasing it — a paraphrase is what gets quoted back with the caution removed. It does not tell you how much is too much, and neither do we: the ASPCA publishes no threshold for any of these plants.

### Are geraniums safe for dogs?

Not according to the ASPCA, which lists geraniums as toxic to dogs and publishes clinical signs for it. That is the answer to the question as asked; we are not going to soften it, and we are not going to tell you a small amount is fine either — the ASPCA publishes no threshold for any of these plants.

### My dog ate geraniums — what now?

Call your veterinarian, or the ASPCA Poison Control at (888) 426-4435. Note which plant, which part, and roughly how much. This page reports what the ASPCA publishes about geraniums; it cannot tell you whether your dog is affected, and no amount is described here as safe.
