Questions about Sweet Pea

Is sweet pea toxic to dogs?

Sweet pea (Lathyrus latifolius) is listed as non-toxic to dogs by the ASPCA, so it is not expected to cause serious harm. That said, non-toxic does not mean safe to eat — plant material is not intended for consumption and can still cause mild stomach upset if ingested.

What happens if my dog eats sweet pea flowers or leaves?

No specific toxicity symptoms are expected, but chewing or swallowing sweet pea plant material may cause mild digestive discomfort such as vomiting or loose stools, especially if a large amount was eaten. Symptoms, if they appear at all, should be mild and short-lived.

How much sweet pea is dangerous for a dog?

Because sweet pea is classified as non-toxic, no dangerous dose threshold is established. However, ingesting a large quantity of any plant material can cause GI upset in dogs regardless of toxicity classification, so it is worth monitoring your dog after any significant ingestion.

What should I do if my dog ate sweet pea?

Monitor your dog for signs of digestive upset such as vomiting, diarrhea, or lethargy. If symptoms are mild, watch closely and ensure access to fresh water. If symptoms persist, worsen, or your dog ate a very large amount, contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435.
